Qt, Color Picker Dialog?
提问by user230821
Is there a color picker dialog for Qt like the following?
Qt 是否有一个颜色选择器对话框，如下所示？
Also it needs to have a OnColorChanged signal which is called when ever the selected color changes. I want to give a live preview when they are changing the colors, that is why.
Also it needs to have a OnColorChanged signal which is called when ever the selected color changes. 我想在他们更改颜色时进行实时预览，这就是原因。
Using google I could only find this one that was a triangle in side of a circle and personally I think it looks ugly.
使用谷歌我只能找到这个是一个圆圈边上的三角形，我个人认为它看起来很丑。

QColorDialogdoes exactly what you want.
QColorDialog正是您想要的。
(It is easy to find when you Ctrl-F through the list of Qt classesfor "color")
（当您通过“颜色”的 Qt 类列表按 Ctrl-F 时很容易找到）

Qt has now a "normal" color picker: http://doc.qt.io/qt-5/qcolordialog.html#details
Qt 现在有一个“普通”颜色选择器：http: //doc.qt.io/qt-5/qcolordialog.html#details
