我有一個使用dragandrop當我關閉應用程序,它崩潰上這條線wxwidget應用:wxwidget應用程序崩潰,當我添加代碼來執行拖放
virtual ~wxDropTargetBase()
{ delete m_dataObject; }
我設置了drapand降了這種方式:
MainWindow::MainWindow() : MainWindowTemplate(NULL), m_fileDropTarget(textSourceFolder)
{
// connect events
this->Connect(wxEVT_IDLE, wxIdleEventHandler(MainWindow::OnIdle));
// set window minimum size - work around bug that ignores outer border and sets min size slightly too small
wxSize minSize = sizerOuter->GetMinSize();
minSize.SetWidth(minSize.GetWidth() + 16);
minSize.SetHeight(minSize.GetHeight() + 16);
SetMinSize(minSize);
Layout();
// set file drop target
SetDropTarget(&m_fileDropTarget);
}
和我
class MyFileDropTarget : public wxFileDropTarget
{
public:
MyFileDropTarget(wxTextCtrl *textCtrl)
{
m_fileTextCtrl = textCtrl;
}
virtual bool wxFileDropTarget::OnDropFiles (wxCoord x, wxCoord y, const wxArrayString &filenames)
{
if (filenames.size() > 0)
{
m_fileTextCtrl->SetValue(filenames.Item(0));
return true;
}
return false;
}
private:
wxTextCtrl *m_fileTextCtrl;
};
的源代碼是什麼問題和浩我可以修復它嗎?
