Tizen Forums

Yes, I did it as you said. But I have other issue. I created a custom CheckButton and can't force Tizen to call OnDraw() where I draw bitmaps for every states checked/unchecked. Even I call OnDraw() on my own, none change is visible. Is is not possible to override OnDraw() for CheckButton? I thought that every Control can override with drawing method. class CustomCheckBox : public Tizen::Ui::Controls::CheckButton { public: CustomCheckBox(); virtual ~CustomCheckBox(); virtual result OnInitializing(void); virtual result OnTerminating(void); virtual result OnDraw(void); ... result CustomCheckBox::OnDraw() { result r = E_SUCCESS; Canvas* pCanvas = GetCanvasN(); Bitmap* bmp; if (pCanvas != null) { bmp = bmpActive; if (!this->IsEnabled()) { bmp = bmpDisabled; } else { if (this->IsSelected()) { bmp = bmpPressed; } } pCanvas->DrawBitmap(*(new Point(0,0)), *bmp); delete pCanvas; } return r; }

If u call Draw for checkbutton it will in turn call OnDraw().

It dosen't work. Neither Draw nor Invalidate call OnDraw() in case CheckButton. Maybe work for others controls.

Yes, is not possible to override OnDraw for CheckButton. I figured it out by subclassing Button + extra code to simulate checkbutton. Easy to implement and work excellent. Of course I use UI Builder.

OnDraw() callback is a method of Container class. but, CheckButton is not inherited from Container class. Therefore, you can't override OnDraw() callback for CheckButton. It can make display error if you call the GetCanvasN() function outside of OnDraw() function. So, I suggest you to make custom control by inheriting Container class.
