我要执行的步骤

1. 创建一个窗口

在窗口的绘制事件中绘制图片

Draw picture in paint event of window

然后创建QGridLayout布局，添加您的窗口

在其上方显示.

假设我要在图片窗口的一部分上添加进度条.我该怎么办

suppose i want to add progress bar, over a portion of picture window. how can i do that

我认为不可能在窗口绘制事件中实现.

i dont think its possible to implement in window paint event.

请帮助我

推荐答案

您可以将进度条添加为QWidget的子级，而无需在布局中添加它.这会将QProgressBar绘制到QWidget中.由于未使用布局，因此必须手动管理QProgressBar的位置.

You can add the progress bar as child of your QWidget without adding it in the layout. This will draw the QProgressBar into the QWidget. Since you are not using the layout you will have to manually manage the position of the QProgressBar.
