PySide.QtGui.QColorDialog class provides a dialog widget for specifying colors.
The color dialog's function is to allow users to choose colors. For example, you might use this in a drawing program to allow the user to set the brush color.
The static functions provide modal color dialogs.
静态 PySide.QtGui.QColorDialog.getColor() function shows the dialog, and allows the user to specify a color. This function can also be used to let users choose a color with a level of transparency: pass the ShowAlphaChannel option as an additional argument.
The user can store PySide.QtGui.QColorDialog.customCount() different custom colors. The custom colors are shared by all color dialogs, and remembered during the execution of the program. Use PySide.QtGui.QColorDialog.setCustomColor() to set the custom colors, and use PySide.QtGui.QColorDialog.customColor() to get them.
标准对话框 example shows how to use PySide.QtGui.QColorDialog as well as other built-in Qt dialogs.
