confused about the layout when comboBox added

[johnson54]

I put several comboBox in a widget, and when I click on the comboBox, it pops up the menu, and at the same time, the whole widget size changed, what should I do to prevent the widget size change. I tried to use grid layout or horizental layout and put spacer around the comboBox, but it still changes size when comboBox pop up menu

@mrjj thanks, I know why this happens, I overload the mouseMoveEvent function, when click on the comboBox, although we didnot see the mouse move, but the mouseMoveEvent is triggered

Hi
That normally do not happen.
Do you use plain comboBoxs ?
