Import r67258 of the wxWidgets trunk, which I expect will before
long become wxWidgets 2.9.2, which in turn is expected to be the last 2.9 release before the 3.0 stable release. Since the full wxWidgets distribution is rather large, I have imported only the parts that we use, on a subdirectory basis: art include/wx/*.* include/wx/aui include/wx/cocoa include/wx/generic include/wx/gtk include/wx/meta include/wx/msw include/wx/osx include/wx/persist include/wx/private include/wx/protocol include/wx/unix src/aui src/common src/generic src/gtk src/msw src/osx src/unix git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@7380 8ced0084-cf51-0410-be5f-012b33b47a6e

/*
|
||||
To use this class, create a wxDragImage when you start dragging, for example:
|
||||
|
||||
void MyTreeCtrl::OnBeginDrag(wxTreeEvent& event)
|
||||
{
|
||||
#ifdef __WXMSW__
|
||||
::UpdateWindow((HWND) GetHWND()); // We need to implement this in wxWidgets
|
||||
#endif
|
||||
|
||||
CaptureMouse();
|
||||
|
||||
m_dragImage = new wxDragImage(* this, itemId);
|
||||
m_dragImage->BeginDrag(wxPoint(0, 0), this);
|
||||
m_dragImage->Move(pt, this);
|
||||
m_dragImage->Show(this);
|
||||
...
|
||||
}
|
||||
|
||||
In your OnMouseMove function, hide the image, do any display updating required,
|
||||
then move and show the image again:
|
||||
|
||||
void MyTreeCtrl::OnMouseMove(wxMouseEvent& event)
|
||||
{
|
||||
if (m_dragMode == MY_TREE_DRAG_NONE)
|
||||
{
|
||||
event.Skip();
|
||||
return;
|
||||
}
|
||||
|
||||
// Prevent screen corruption by hiding the image
|
||||
if (m_dragImage)
|
||||
m_dragImage->Hide(this);
|
||||
|
||||
// Do some updating of the window, such as highlighting the drop target
|
||||
...
|
||||
|
||||
#ifdef __WXMSW__
|
||||
if (updateWindow)
|
||||
::UpdateWindow((HWND) GetHWND());
|
||||
#endif
|
||||
|
||||
// Move and show the image again
|
||||
m_dragImage->Move(event.GetPosition(), this);
|
||||
m_dragImage->Show(this);
|
||||
}
|
||||
|
||||
Eventually we end the drag and delete the drag image.
|
||||
|
||||
void MyTreeCtrl::OnLeftUp(wxMouseEvent& event)
|
||||
{
|
||||
...
|
||||
|
||||
// End the drag and delete the drag image
|
||||
if (m_dragImage)
|
||||
{
|
||||
m_dragImage->EndDrag(this);
|
||||
delete m_dragImage;
|
||||
m_dragImage = NULL;
|
||||
}
|
||||
ReleaseMouse();
|
||||
}

||||

||||
|
||||
/*
|
||||
Notes for Unix version:
|
||||
Can we simply use cursors instead, creating a cursor dynamically, setting it into the window
|
||||
in BeginDrag, and restoring the old cursor in EndDrag?
|
||||
For a really bog-standard implementation, we could simply use a normal dragging cursor
|
||||
and ignore the image.
