I want to put a png image as background in QToolButton. But I am not able to get the transparent portions in the button. The transparent portions are showing as white in my QToolButton. Can anybody suggest how to remove the white portions as transparent ?

推荐答案

我想有什么东西错了你的PNG文件。下面code：

I suppose there's something wrong with your png file. The following code:

QToolButton button;
button.setIcon(QIcon("E:/delete.png"));
button.setIconSize(QSize(256, 256));
button.show();

工作正常，我（当然电子商务：/delete.png有透明背景）。

works fine for me (of course E:/delete.png have transparent background).

请确保您保存透明度的PNG。

Make sure you save transparency for your png.
