PageControl question, about self-painting.

我的马甲

A breakpoint is set in the OnDrawTab event. Why is there no pause? And no effect was drawn.
I want to draw a small cross in the upper right corner of the tab (to keep the original text part), how to draw a picture?

Is the OwnerDraw property of PageControl set to true? ? ?

Haha, thanks, really.
Alas, there is still less work done.

What's wrong with drawing?
After setting OwnerDraw, you can draw your things in the OnDrawTab event function. . .
The parameter TabIndex is the index of the drawn Tab, Rect is the rectangular area of ​​the drawn Tab, and Active is whether the drawn Tab is currently activated
After getting these things, you can draw anything on the Tab. . .

Well, it was just drawn. V_V

TIcon * Icon = NULL;
ImageList1-> GetIcon (0, Icon); // This sentence can not get the icon. There is obviously one in it. Icon is still NULL.
Control-> Canvas-> Draw (0,3, Icon);

Sorry, no initialization.
