隐藏 QComboBox 标签中的图标 [英] Hide Icon from the label of QComboBox

问题描述

我正在尝试实现一个 QComboBox，它包含 QIcon 和 QString，如下所示:

I am trying to implement a QComboBox, which holds QIcon and QString, like this:

QComboBox.addItem(icon, label);

我希望图标在下拉列表中可见，但在工具栏中不可见.选择项目后，只有字符串应该可见.

I want the icons to be visible in the drop-down list, but not in the toolbar. Only the string should be visible after item selection.

有没有简单的方法可以做到这一点?

Is there an easy way to do this?

推荐答案

最好的方法是设置一个委托并自己绘制项目.然后您可以选择何时或不绘制图标(decorationRole)，您可以选择不为当前索引的索引绘制图标.我可以找到一个关于如何在组合框上使用委托的快速示例:http://programmingexamples.net/wiki/Qt/Delegates/ComboBoxDelegate

The best way is to set a delegate and to draw the items yourself. Then you can choose when or not to draw the icon ( decorationRole ), you can choose not to draw the icon for the index which is the current index. I could find a quick example on how to use a delegate on combobox: http://programmingexamples.net/wiki/Qt/Delegates/ComboBoxDelegate

但恐怕这不是最简单的方法.祝你好运！

But I am afraid it is not the most easist of the ways. Good luck!
