QWinWidget display to display Qt widget on MFC window
EmmanuelC last edited by aha_1980
I'm trying to display a Qt widget (a QLineEdit to be precise) in a MFC window. To do so, I'm using QWinWidget.
It displays well the QLineEdit, but the problem I have is that when I want to update the field and click on it, it's disappearing...
Then when I click on another window in my application, it's reapprearing, and is well updated if I changed the text inside of it (even if it had disappeared)
Anyone has an idea on what's going wrong here?
Here is my code :
CRect ControlArea2; m_Control3.GetClientRect(ControlArea2); HWND hWnd_TransfFunction = m_Control3.GetSafeHwnd(); QWinWidget w(hWnd_TransfFunction, 0, 0); QWidget *widget = new QWidget(&w); QHBoxLayout *hbox = new QHBoxLayout(widget); QLabel *label = new QLabel("Enter text:", widget); QLineEdit *edit = new QLineEdit(widget); hbox->addWidget(label); hbox->addWidget(edit); widget->move(0, 0); widget->setBackgroundRole(QPalette::Base); w.setGeometry(ControlArea2.left, ControlArea2.top, ControlArea2.Width(), ControlArea2.Height()); w.setFixedSize(ControlArea2.Width(), ControlArea2.Height()); w.show();
What Qt version are you using?
QtWinMigrate might have issue in Qt5+

@mrjj I am using Qt 5.12.3. So it might be the problem?
Do you think I should try an older version like Qt 5.8?
