\index{wxDragResult}wxDragResult is defined as follows:

{\small\begin{verbatim}

enum wxDragResult
|
|
{
|
|
wxDragError, // error prevented the d&d operation from completing

wxDragNone, // drag target didn't accept the data
|
|
wxDragCopy, // the data was successfully copied
|
|
wxDragMove, // the data was successfully moved
|
|
wxDragCancel // the operation was cancelled by user (not an error)

\membersection{wxDropSource::wxDropSource}\label{wxdropsourcewxdropsource}
|
|
|
|
\func{}{wxDropSource}{\param{wxWindow }{*win = NULL}}
|
|
|
|
Default/wxGTK-specific constructor. If you use the default constructor you must
|
|
call \helpref{wxDropSource::SetData}{wxdropsourcesetdata} later.
|
|
|
|
{\it win} is only used by wxGTK. TODO: in what circumstances?
|
|
|
|
\func{}{wxDropSource}{\param{wxDataObject }{\&data}, \param{wxWindow }{*win = NULL}}
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{data}{A reference to the \helpref{data object}{wxdataobject} associated with the drop source.}
|
|
|
|
\docparam{win}{Only used by wxGTK. TODO}
|
|
|
|
\membersection{wxDropSource::\destruct{wxDropSource}}\label{wxdropsourcedtor}
|
|
|
|
\func{virtual }{\destruct{wxDropSource}}{\void}
|
|
|
|
\membersection{wxDropSource::SetData}\label{wxdropsourcesetdata}
|
|
|
|
\func{void}{SetData}{\param{wxDataObject }{\&data}}
|
|
|
|
Sets the data \helpref{data object}{wxdataobject} associated with the drop source.
|
|
|
|
\membersection{wxDropSource::DoDragDrop}\label{wxdropsourcedodragdrop}
|
|
|
|
\func{virtual wxDragResult}{DoDragDrop}{\param{bool }{bAllowMove = FALSE}}
|
|
|
|
Do it (call this in response to a mouse button press, for example).
|
|
|
|
If {\bf bAllowMove} is FALSE, data can only be copied.
|
|
|
|
\membersection{wxDropSource::GiveFeedback}\label{wxdropsourcegivefeedback}
|
|
|
|
\func{virtual bool}{GiveFeedback}{\param{wxDragResult }{effect}, \param{bool }{bScrolling}}
|
|
|
|
Overridable: you may give some custom UI feedback during the drag and drop operation
|
|
in this function. It is called on each mouse move, so your implementation must not be too
|
|
slow.
|
|
|
|
\wxheading{Parameters}
|
|
|
|
\docparam{effect}{The effect to implement. One of wxDragCopy, wxDragMove.}
|
|
|
|
\docparam{bScrolling}{TRUE if the window is scrolling.}
|
|
|
|
\wxheading{Return value}
|
|
|
|
Return FALSE if you want default feedback, or TRUE if you implement your own
|
|
feedback.
