\section{\class{wxWindow}}\label{wxwindow}
|
|
|
|
wxWindow is the base class for all windows. Any
|
|
children of the window will be deleted automatically by the destructor
|
|
before the window itself is deleted.
|
|
|
|
\wxheading{Derived from}

|
\wxheading{Window styles}
|
|
|
|
The following styles can apply to all windows, although they will not always make sense for a particular
|
|
window class.
|
|
|
|
\twocolwidtha{5cm}%
|
|
\begin{twocollist}\itemsep=0pt
|
|
\twocolitem{\windowstyle{wxSIMPLE\_BORDER}}{Displays a thin border around the window. wxBORDER is the old name
|
|
for this style.}
|
|
\twocolitem{\windowstyle{wxDOUBLE\_BORDER}}{Displays a double border. Windows only.}
|
|
\twocolitem{\windowstyle{wxSUNKEN\_BORDER}}{Displays a sunken border.}
|
|
\twocolitem{\windowstyle{wxRAISED\_BORDER}}{Displays a raised border.}
|
|
\twocolitem{\windowstyle{wxSTATIC\_BORDER}}{Displays a border suitable for a static control.}
|
|
\twocolitem{\windowstyle{wxTRANSPARENT\_WINDOW}}{The window is transparent, that is, it will not receive paint
|
|
events. Windows only.}
|
|
\twocolitem{\windowstyle{wxNO\_3D}}{Prevents the children of this window taking on 3D styles, even though
|
|
the application-wide policy is for 3D controls. Windows only.}
|
|
\twocolitem{\windowstyle{wxTAB\_TRAVERSAL}}{Use this to enable tab traversal for non-dialog windows.}
|
|
\twocolitem{\windowstyle{wxVSCROLL}}{Use this style to enable a vertical scrollbar.}
|
|
\twocolitem{\windowstyle{wxHSCROLL}}{Use this style to enable a horizontal scrollbar.}
|
|
\twocolitem{\windowstyle{wxCLIP\_CHILDREN}}{Use this style to eliminate flicker caused by the background being
|
|
repainted, then children being painted over them. Windows-only.}

|
|
\param{const wxPoint\& }{pos = wxDefaultPosition},
|
|
\param{const wxSize\& }{size = wxDefaultSize},
|
|
\param{long }{style = 0},
|
|
\param{const wxString\& }{name = wxPanelNameStr}}
|
|
|
|

|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{parent}{Pointer to a parent window.}
|
|
|
|
\docparam{id}{Window identifier. If -1, will automatically create an identifier.}
|
|
|
|
\docparam{pos}{Window position. wxDefaultPosition is (-1, -1) which indicates that wxWindows
|
|
should generate a default position for the window. If using the wxWindow class directly, supply
|
|
an actual position.}
|
|
|
|
\docparam{size}{Window size. wxDefaultSize is (-1, -1) which indicates that wxWindows
|
|
should generate a default size for the window.}

\membersection{wxWindow::\destruct{wxWindow}}
|
|
|
|
\func{}{\destruct{wxWindow}}{\void}
|
|
|
|
Destructor. Deletes all subwindows, then deletes itself. Instead of using
|
|
the {\bf delete} operator explicitly, you should normally
|
|
use \helpref{wxWindow::Destroy}{wxwindowdestroy} so that wxWindows
|
|
can delete a window only when it is safe to do so, in idle time.

\membersection{wxWindow::AddChild}
|
|
|
|
\func{virtual void}{AddChild}{\param{wxWindow* }{child}}
|
|
|
|
Adds a child window. This is called automatically by window creation
|
|
functions so should not be required by the application programmer.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{child}{Child window to add.}
|
|
|
|
\membersection{wxWindow::CaptureMouse}\label{wxwindowcapturemouse}
|
|
|
|
\func{virtual void}{CaptureMouse}{\void}
|
|
|
|
Directs all mouse input to this window. Call \helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse} to
|
|
release the capture.

\membersection{wxWindow::Center}\label{wxwindowcenter}
|
|
|
|
\func{void}{Center}{\param{int}{ direction}}
|
|
|
|
A synonym for \helpref{Centre}{wxwindowcentre}.
|
|
|
|
\membersection{wxWindow::Centre}\label{wxwindowcentre}
|
|
|
|
\func{virtual void}{Centre}{\param{int}{ direction = wxHORIZONTAL}}
|
|
|
|
Centres the window.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{direction}{Specifies the direction for the centering. May be {\tt wxHORIZONTAL}, {\tt wxVERTICAL}\rtfsp
|
|
or {\tt wxBOTH}.}
|
|
|
|
\wxheading{Remarks}
|
|
|
|
The actual behaviour depends on the derived window. For a frame or dialog box,
|
|
centring is relative to the whole display. For a panel item, centring is
|
|
relative to the panel.

\membersection{wxWindow::Clear}\label{wxwindowclear}
|
|
|
|
\func{void}{Clear}{\void}
|
|
|
|
Clears the window by filling it with the current background colour.
|
|
|
|
\membersection{wxWindow::ClientToScreen}
|
|
|
|
\constfunc{virtual void}{ClientToScreen}{\param{int* }{x}, \param{int* }{y}}
|
|
|
|
\constfunc{virtual wxPoint}{ClientToScreen}{\param{const wxPoint\&}{ pt}}
|
|
|
|
Converts to screen coordinates from coordinates relative to this window.
|
|
|
|
\docparam{x}{A pointer to a integer value for the x coordinate. Pass the client coordinate in, and
|
|
a screen coordinate will be passed out.}
|
|
|
|
\docparam{y}{A pointer to a integer value for the y coordinate. Pass the client coordinate in, and
|
|
a screen coordinate will be passed out.}
|
|
|
|
\docparam{pt}{The client position for the second form of the function.}
|
|
|
|
\membersection{wxWindow::Close}\label{wxwindowclose}
|
|
|
|
\func{virtual bool}{Close}{\param{const bool}{ force = FALSE}}
|
|
|
|
The purpose of this call is to provide a safer way of destroying a window than using
|
|
the {\it delete} operator.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{force}{FALSE if the window's close handler should be able to veto the destruction
|
|
of this window, TRUE if it cannot.}
|
|
|
|
\wxheading{Remarks}
|
|
|
|
Close calls the \helpref{close handler}{wxcloseevent} for the window, providing an opportunity for the window to
|
|
choose whether to destroy the window.
|
|
|
|
The close handler should check whether the window is being deleted forcibly,
|
|
using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}, in which case it should
|
|
destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
|
|
|
|
Applies to managed windows (wxFrame and wxDialog classes) only.

|
|
|
\func{wxPoint}{ConvertDialogToPixels}{\param{const wxPoint\&}{ pt}}
|
|
|
|
\func{wxSize}{ConvertDialogToPixels}{\param{const wxSize\&}{ sz}}
|
|
|
|
Converts a point or size from dialog units to pixels.
|
|
|
|
For the x dimension, the dialog units are multiplied by the average character width
|
|
and then divided by 4.
|
|
|
|
For the y dimension, the dialog units are multiplied by the average character height
|
|
and then divided by 8.
|
|
|
|
\wxheading{Remarks}
|
|
|
|
Dialog units are used for maintaining a dialog's proportions even if the font changes.
|
|
Dialogs created using Dialog Editor optionally use dialog units.
|
|
|
|
You can also use these functions programmatically. A convenience macro is defined:
|
|
|
|
{\small
|
|
\begin{verbatim}
|
|
#define wxDLG_UNIT(parent, pt) parent->ConvertDialogToPixels(pt)
|
|
\end{verbatim}

|
\func{wxPoint}{ConvertPixelsToDialog}{\param{const wxPoint\&}{ pt}}
|
|
|
|
\func{wxSize}{ConvertPixelsToDialog}{\param{const wxSize\&}{ sz}}
|
|
|
|
Converts a point or size from pixels to dialog units.
|
|
|
|
For the x dimension, the pixels are multiplied by 4 and then divided by the average
|
|
character width.
|
|
|
|
For the y dimension, the pixels are multipled by 8 and then divided by the average
|
|
character height.
|
|
|
|
\wxheading{Remarks}
|
|
|
|
Dialog units are used for maintaining a dialog's proportions even if the font changes.
|
|
Dialogs created using Dialog Editor optionally use dialog units.

|
|
|
|
\membersection{wxWindow::Destroy}\label{wxwindowdestroy}
|
|
|
|
\func{virtual bool}{Destroy}{\void}
|
|
|
|
Destroys the window safely. Use this function instead of the delete operator, since
|
|
different window classes can be destroyed differently. Frames and dialogs
|
|
are not destroyed immediately when this function is called - they are added
|
|
to a list of windows to be deleted on idle time, when all the window's events
|
|
have been processed. This prevents problems with events being sent to non-existant
|
|
windows.
|
|
|
|
\wxheading{Return value}
|
|
|
|
TRUE if the window has either been successfully deleted, or it has been added
|
|
to the list of windows pending real deletion.
|
|
|
|
\membersection{wxWindow::DestroyChildren}
|
|
|
|
\func{virtual void}{DestroyChildren}{\void}
|

\constfunc{virtual void}{GetPosition}{\param{int* }{x}, \param{int* }{y}}
|
|
|
|
This gets the position of the window in pixels, relative to the parent window or
|
|
if no parent, relative to the whole display.
|
|
|
|
\wxheading{Parameters}
|
|
|

|
\membersection{wxWindow::GetLabel}
|
|
|
|
\constfunc{virtual wxString\& }{GetLabel}{\void}
|
|
|
|
Generic way of getting a label from any window, for
|
|
identification purposes.
|
|
|
|
\wxheading{Remarks}
|
|
|
|
The interpretation of this function differs from class to class.
|
|
For frames and dialogs, the value returned is the title. For buttons or static text controls, it is
|
|
the button text. This function can be useful for meta-programs (such as testing
|
|
tools or special-needs access programs) which need to identify windows
|
|
by name.
|
|
|
|
\membersection{wxWindow::GetName}\label{wxwindowgetname}
|
|
|
|
\constfunc{virtual wxString\& }{GetName}{\void}
|
|
|
|
Returns the window's name.
|
|
|
|
\wxheading{Remarks}
|
|
|
|
This name is not guaranteed to be unique; it is up to the programmer to supply an appropriate
|
|
name in the window constructor or via \helpref{wxWindow::SetName}{wxwindowsetname}.

\wxheading{Remarks}
|
|
|
|
This member function is called in response to a keypress. To intercept this event,
|
|
use the EVT\_CHAR macro in an event table definition. Your {\bf OnChar} handler may call this
|
|
default function to achieve default keypress functionality.
|
|
|
|
Note that the ASCII values do not have explicit key codes: they are passed as ASCII
|
|
values.
|
|
|
|
Note that not all keypresses can be intercepted this way. If you wish to intercept special
|
|
keys, such as shift, control, and function keys, then you will need to use \helpref{wxWindow::OnKeyDown}{wxwindowonkeydown} or
|
|
\helpref{wxWindow::OnKeyUp}{wxwindowonkeyup}.
|
|
|

This member is called to allow the window to intercept keyboard events
|
|
before they are processed by child windows.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{event}{Object containing keypress information. See \helpref{wxKeyEvent}{wxkeyevent} for
|

|
|
|
|
\wxheading{Remarks}
|
|
|
|
This member function is called in response to a keypress, if the window is active. To intercept this event,
|
|
use the EVT\_CHAR\_HOOK macro in an event table definition. If you do not process a particular
|
|
keypress, call \helpref{wxEvent::Skip}{wxeventskip} to allow default processing.
|
|
|
|
An example of using this function is in the implementation of escape-character processing for wxDialog,
|
|
where pressing ESC dismisses the dialog by {\bf OnCharHook} 'forging' a cancel button press event.
|
|
|
|
Note that the ASCII values do not have explicit key codes: they are passed as ASCII

values.

Called when the user has tried to close a a frame

or dialog box using the window manager (X) or system menu (Windows).
|
|
|
|
{\bf Note:} This is an obsolete function retained for backward compatibility.

It is superceded by the \helpref{wxWindow::OnCloseWindow}{wxwindowonclosewindow} event

\wxheading{Return value}
|
|
|
|
If TRUE is returned by OnClose, the window will be deleted by the system, otherwise the

|
you may delete other windows.
|
|

\func{void}{OnCloseWindow}{\param{wxCloseEvent\& }{event}}
|
|
|
|
This is an event handler function called when the user has tried to close a a frame
|
|
or dialog box using the window manager (X) or system menu (Windows). It is
|
|
called via the \helpref{wxWindow::Close}{wxwindowclose} function, so
|
|
that the application can also invoke the handler programmatically.
|
|
|
|
Use the EVT\_CLOSE event table macro to handle close events.
|
|
|
|
You should check whether the application is forcing the deletion of the window
|
|
using \helpref{wxCloseEvent::GetForce}{wxcloseeventgetforce}. If this is TRUE,
|
|
destroy the window using \helpref{wxWindow::Destroy}{wxwindowdestroy}.
|
|
If not, it is up to you whether you respond by destroying the window.
|
|
|
|
(Note: GetForce is now superceded by CanVeto. So to test whether forced destruction of
|
|
the window is required, test for the negative of CanVeto. If CanVeto returns FALSE,
|
|
it is not possible to skip window deletion.)
|
|
|
|
If you don't destroy the window, you should call \helpref{wxCloseEvent::Veto}{wxcloseeventveto} to
|
|
let the calling code know that you did not destroy the window. This allows the \helpref{wxWindow::Close}{wxwindowclose} function
|
|
to return TRUE or FALSE depending on whether the close instruction was honoured or not.
|
|
|
|
\wxheading{Remarks}
|
|
|
|
The \helpref{wxWindow::OnClose}{wxwindowonclose} virtual function remains
|
|
for backward compatibility with earlier versions of wxWindows. The
|
|
default {\bf OnCloseWindow} handler for wxFrame and wxDialog will call {\bf OnClose},
|
|
destroying the window if it returns TRUE or if the close is being forced.

\func{void}{OnMenuHighlight}{\param{wxMenuEvent\& }{event}}
|
|
|
|
Called when a menu select is received from a menu bar: that is, the

|
mouse cursor is over a menu item, but the left mouse button has not been
|
|
pressed.
|
|
|
|
\wxheading{Parameters}

|

\func{void}{OnPaint}{\param{wxPaintEvent\& }{event}}
|
|
|
|
Sent to the event handler when the window must be refreshed.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{event}{Paint event. For more information, see \helpref{wxPaintEvent}{wxpaintevent}.}
|
|
|
|
\wxheading{Remarks}
|
|
|
|
Use the EVT\_PAINT macro in an event table definition to intercept paint events.
|
|
|
|
In a paint event handler, the application should always create a \helpref{wxPaintDC}{wxpaintdc} object.
|
|
|
|
For example:
|
|
|
|
\small{%
|
|
\begin{verbatim}
|
|
void MyWindow::OnPaint(wxPaintEvent& event)
|
|
{
|
|
wxPaintDC dc(this);
|
|
|
|
DrawMyDocument(dc);
|
|
}
|
|
\end{verbatim}
|
|
}%
|
|
|
|
You can optimize painting by retrieving the rectangles
|
|
that have been damaged and only repainting these. The rectangles are in
|
|
terms of the client area, and are unscrolled, so you will need to do
|
|
some calculations using the current view position to obtain logical,
|
|
scrolled units.
|
|
|
|
Here is an example of using the \helpref{wxRegionIterator}{wxregioniterator} class:
|
|
|
|
{\small%
|
|
\begin{verbatim}
|
|
// Called when window needs to be repainted.
|
|
void MyWindow::OnPaint(wxPaintEvent& event)
|
|
{
|
|
wxPaintDC dc(this);
|
|
|
|
// Find Out where the window is scrolled to
|
|
int vbX,vbY; // Top left corner of client
|
|
ViewStart(&vbX,&vbY);
|
|
|
|
int vX,vY,vW,vH; // Dimensions of client area in pixels
|
|
wxRegionIterator upd(GetUpdateRegion()); // get the update rect list
|
|
|
|
while (upd)
|
|
{
|
|
vX = upd.GetX();
|
|
vY = upd.GetY();
|
|
vW = upd.GetW();
|
|
vH = upd.GetH();
|
|
|
|
// Alternatively we can do this:
|
|
// wxRect rect;
|
|
// upd.GetRect(&rect);
|
|
|
|
// Repaint this rectangle
|
|
...some code...
|
|
|
|
upd ++ ;
|
|
}
|
|
}
|
|
\end{verbatim}

\wxheading{Parameters}
|
|
|
|
\docparam{handler}{Specifies the handler to be pushed.}
|
|
|
|
\wxheading{Remarks}
|
|
|
|
An event handler is an object that is capable of processing the events
|
|
sent to a window. By default, the window is its own event handler, but
|
|
an application may wish to substitute another, for example to allow
|
|
central implementation of event-handling for a variety of different
|
|
window classes.
|
|
|
|
\helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} allows
|
|
an application to set up a chain of event handlers, where an event not handled by one event handler is
|
|
handed to the next one in the chain. Use \helpref{wxWindow::PopEventHandler}{wxwindowpopeventhandler} to
|
|
remove the event handler.

choosing one, which could clash with other ones.

\docparam{refresh}{TRUE to redraw the scrollbar, FALSE otherwise.}
|
|
|
|
\wxheading{Remarks}
|
|
|
|
Let's say you wish to display 50 lines of text, using the same font.
|
|
The window is sized so that you can only see 16 lines at a time.
|
|
|
|
You would use:
|
|
|
|
{\small%
|
|
\begin{verbatim}
|
|
SetScrollbar(wxVERTICAL, 0, 16, 50);
|
|
\end{verbatim}
|
|
}
|
|
|
|
Note that with the window at this size, the thumb position can never go
|
|
above 50 minus 16, or 34.
|
|
|
|
You can determine how many lines are currently visible by dividing the current view
|
|
size by the character height in pixels.
|
|
|
|
When defining your own scrollbar behaviour, you will always need to recalculate
|
|
the scrollbar settings when the window size changes. You could therefore put your
|
|
scrollbar calculations and SetScrollbar
|
|
call into a function named AdjustScrollbars, which can be called initially and also
|
|
from your \helpref{wxWindow::OnSize}{wxwindowonsize} event handler function.

Sets the page size of one of the built-in scrollbars.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{orientation}{Determines the scrollbar whose page size is to be set. May be wxHORIZONTAL or wxVERTICAL.}
|
|
|
|
\docparam{pageSize}{Page size in scroll units.}
|
|
|
|
\docparam{refresh}{TRUE to redraw the scrollbar, FALSE otherwise.}
|
|
|
|
\wxheading{Remarks}
|
|
|
|
The page size of a scrollbar is the number of scroll units that the scroll thumb travels when you
|
|
click on the area above/left of or below/right of the thumb. Normally you will want a whole visible
|
|
page to be scrolled, i.e. the size of the current view (perhaps the window client size). This
|
|
value has to be adjusted when the window is resized, since the page size will have changed.
|
|
|
|
In addition to specifying how far the scroll thumb travels when paging, in Motif and some versions of Windows
|
|
the thumb changes size to reflect the page size relative to the length of the document. When the
|
|
document size is only slightly bigger than the current view (window) size, almost all of the scrollbar
|
|
will be taken up by the thumb. When the two values become the same, the scrollbar will (on some systems)
|
|
disappear.
|
|
|
|
Currently, this function should be called before SetPageRange, because of a quirk in the Windows
|
|
handling of pages and ranges.

|
|
\func{virtual void}{SetScrollRange}{\param{int }{orientation}, \param{int }{range}, \param{const bool }{refresh = TRUE}}
|
|
|
|
Sets the range of one of the built-in scrollbars.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{orientation}{Determines the scrollbar whose range is to be set. May be wxHORIZONTAL or wxVERTICAL.}

|
\wxheading{Remarks}
|
|
|
|
The range of a scrollbar is the number of steps that the thumb may travel, rather than the total
|
|
object length of the scrollbar. If you are implementing a scrolling window, for example, you
|
|
would adjust the scroll range when the window is resized, by subtracting the window view size from the
|
|
total virtual window size. When the two sizes are the same (all the window is visible), the range goes to zero
|
|
and usually the scrollbar will be automatically hidden.

|
|
|
\docparam{sizeFlags}{Indicates the interpretation of other parameters. It is a bit list of the following:
|
|
|
|
{\bf wxSIZE\_AUTO\_WIDTH}: a -1 width value is taken to indicate
|
|
a wxWindows-supplied default width.\\
|
|
{\bf wxSIZE\_AUTO\_HEIGHT}: a -1 height value is taken to indicate
|
|
a wxWindows-supplied default width.\\
|
|
{\bf wxSIZE\_AUTO}: -1 size values are taken to indicate
|
|
a wxWindows-supplied default size.\\
|
|
{\bf wxSIZE\_USE\_EXISTING}: existing dimensions should be used
|
|
if -1 values are supplied.\\
|

{\bf wxSIZE\_ALLOW\_MINUS\_ONE}: allow dimensions of -1 and less to be interpreted
|
|
as real dimensions, not default values.

|
|
|
|
The second form is a convenience for calling the first form with default

\func{virtual void}{SetClientSize}{\param{const wxSize\&}{ size}}
|
|
|
|
This sets the size of the window client area in pixels. Using this function to size a window
|
|
tends to be more device-independent than \helpref{wxWindow::SetSize}{wxwindowsetsize}, since the application need not
|
|
worry about what dimensions the border or title bar have when trying to fit the window
|
|
around panel items, for example.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{width}{The required client area width.}

\membersection{wxWindow::SetCursor}\label{wxwindowsetcursor}

|
|
|
|
\docparam{cursor}{Specifies the cursor that the window should normally display.}
|
|
|
|
\wxheading{Remarks}
|
|
|
|
Under Windows, you sometimes need to call ::wxSetCursor in addition to this

|
function if you want the cursor to change immediately, because under Windows,
|
|
wxWindows only sets the global cursor when it detects mouse movement.

\wxheading{Parameters}
|
|
|
|
\docparam{handler}{Specifies the handler to be set.}
|
|
|
|
\wxheading{Remarks}
|
|
|
|
An event handler is an object that is capable of processing the events
|
|
sent to a window. By default, the window is its own event handler, but
|
|
an application may wish to substitute another, for example to allow
|
|
central implementation of event-handling for a variety of different
|
|
window classes.
|
|
|
|
It is usually better to use \helpref{wxWindow::PushEventHandler}{wxwindowpusheventhandler} since
|
|
this sets up a chain of event handlers, where an event not handled by one event handler is
|
|
handed to the next one in the chain.
