删除QComboBox“下拉”动画 [英] Removing QComboBox "Drop-Down" Animation

问题描述

我使用Qt 4.8，并希望摆脱下拉动画时点击一个QComboBox。我也想移动它一点。到目前为止，我一直在寻找重新实现showPopup和hidePopup，但不能弄清楚如何使其工作。

I am using Qt 4.8 and would like to get rid of the "Drop-Down" animation when clicking on a QComboBox. I also want to move it a bit. So far I've been looking at re-implementing showPopup and hidePopup but can't figure out how to make it work.

此外，每次我尝试移动或style使用CSS有一个白色的背景，总是存在。 （见图）。

Additionally, every time I try to move or style using CSS there is a white background that is always there. (See picture). Any help would be appreciated.

推荐答案

使用 QApplication :: setEffectEnabled ：

QApplication::setEffectEnabled(Qt::UI_AnimateCombo, false);
