drawControl not being called for custom styled elements

[ateek.ujjawal]

@Christian-Ehrlicher I tried overriding that function as well, but it does not get called.

Also if I wanted to draw separate elements, like the add page and sub page of the scrollbar, how would it be possible with the drawControl/drawComplexControl?

[Christian Ehrlicher]

Override those functions and reimplement what you want.
You should also make sure that you really use your style.

@Christian-Ehrlicher Tried doing that, neither the drawControl or drawComplexControl get called. What might I be doing wrong?

@ateek-ujjawal said in drawControl not being called for custom styled elements:

What might I be doing wrong?

You are not using your style as I already told you.

@Christian-Ehrlicher Is this not the correct way of doing it?

  _ui.slicingScrollBar->setStyle(new CustomStyle);

The slicingScrollBar is a QScrollBar. The CustomStyle is defined as follows:

class CustomStyle : public QProxyStyle {
  Q_OBJECT

 public:
  CustomStyle();
  ~CustomStyle() {};

  void drawPrimitive(PrimitiveElement pe, const QStyleOption* opt, QPainter* p,
                     const QWidget* widget) const override;

  void drawControl(ControlElement ce, const QStyleOption* opt, QPainter* p,
                   const QWidget* w = nullptr) const override;

  void drawComplexControl(ComplexControl cc, const QStyleOptionComplex* opt,
                          QPainter* p,
                          const QWidget* widget = nullptr) const override;
};

Hi,

What if you set it on QApplication ?

[ateek.ujjawal]

@SGaist Still the same result.

[Christian Ehrlicher]

Start from the example in https://doc.qt.io/qt-6/qproxystyle.html#details and see what happens.

[ateek.ujjawal]

@Christian-Ehrlicher Uh, I don't see how overriding the style hint would help. I searched the QStyle enum for options I needed and I came up with nothing useful.

[Christian Ehrlicher]

You should start with this example to see if it works and then add your function to find out what is going wrong...
