\section{\class{wxContextMenuEvent}}\label{wxcontextmenuevent}
|
|
|
|
This class is used for context menu events, sent to give
|
|
the application a chance to show a context (popup) menu.
|
|
|
|
Note that if \helpref{GetPosition}{wxcontextmenueventgetposition} returns wxDefaultPosition, this means that the event originated
|
|
from a keyboard context button event, and you should compute a suitable position yourself,
|
|
for example by calling \helpref{wxGetMousePosition}{wxgetmouseposition}.
|
|
|
|
When a keyboard context menu button is pressed on Windows, a right-click event with default position is sent first,
|
|
and if this event is not processed, the context menu event is sent. So if you process mouse events and you find your context menu event handler
|
|
is not being called, you could call wxEvent::Skip for mouse right-down events.

functions that take a wxContextMenuEvent argument.

\func{}{wxContextMenuEvent}{\param{WXTYPE }{id = 0}, \param{int }{id = 0}, \param{const wxPoint\&}{ pos=wxDefaultPosition}}

Constructor.

\membersection{wxContextMenuEvent::GetPosition}\label{wxcontextmenueventgetposition}
|
|
|
|
\constfunc{wxPoint}{GetPosition}{\void}
|
|
|
|
Returns the position in screen coordinates at which the menu should be shown. Use \helpref{wxWindow::ScreenToClient}{wxwindowscreentoclient} to
|
|
convert to client coordinates. You can also omit a position from \helpref{wxWindow::PopupMenu}{wxwindowpopupmenu} in order to use
|
|
the current mouse pointer position.
|
|
|
|
If the event originated from a keyboard event, the value returned from this function will be wxDefaultPosition.
|
|
|
|
\membersection{wxContextMenuEvent::SetPosition}\label{wxcontextmenueventsetposition}
|
|
|
|
\func{void}{SetPosition}{\param{const wxPoint\&}{ point}}
|
|
|
|
Sets the position at which the menu should be shown.
