The following class members are part of the Qt 3 support layer. They are provided to help you port old code to Qt 4. We advise against using them in new code.
Constant | Value |
---|---|
QWidget::WidgetOrigin | 0 |
QWidget::ParentOrigin | 1 |
QWidget::WindowOrigin | 2 |
QWidget::AncestorOrigin | 3 |
Returns the color role used for painting the widget's background.
Use QPalette(backgroundRole(()) instead.
Always returns QPoint().
Always returns WindowOrigin.
Use windowTitle() instead.
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
Use the childAt() overload that doesn't have an includeThis parameter.
For example, if you have code like
return widget->childAt(x, y, true);
you can rewrite it as
QWidget *child = widget->childAt(x, y, true); if (child) return child; if (widget->rect().contains(x, y)) return widget;
