Question

当更换滑块时，如何使QListView的项目图标调整大小？它似乎是在调整项目的大小，但不是图标。

我尝试同时调用这两种方法，但两者均无效。理想情况下，我不希望调用setGridSize，因为这会导致小部件忽略我打算使用的setSpacing(5)。

self.uiListView.setGridSize(iconSize)
self.uiListView.setIconSize(iconSize)

我发现这是我图标的原始大小为64x64的结果。 Qt不会将图标的大小调整为大于其原始大小。只会将图标的大小调整为较小的大小。

self.uiListView.setIconSize(QtCore.QSize(64,64))

动态调整QListView项目的图标大小
