继承 QDialog .
The 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 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 customCount () different custom colors. The custom colors are shared by all color dialogs, and remembered during the execution of the program. Use setCustomColor () 去设置 custom colors, and use customColor () to get them.
标准对话框 example shows how to use QColorDialog as well as other built-in Qt dialogs.
This enum specifies various options that affect the look and feel of a color dialog.
| 常量 | 值 | 描述 |
|---|---|---|
| QColorDialog.ShowAlphaChannel | 0x00000001 | Allow the user to select the alpha component of a color. |
| QColorDialog.NoButtons | 0x00000002 | Don't display OK and Cancel buttons. (Useful for "live dialogs".) |
| QColorDialog.DontUseNativeDialog | 0x00000004 | Use Qt's standard color dialog on the Mac instead of the operating system native color dialog. |

另请参阅 QDialog.done ().
Pops up a modal color dialog with the given window title (or "Select Color" if none is specified), lets the user choose a color, and returns that color. The color is initially set to initial . The dialog is a child of parent . It returns an invalid (see QColor.isValid ()) color if the user cancels the dialog.
options argument allows you to customize the 对话框。
On Symbian, this static function will use the native color dialog and not a QColorDialog . On Symbian the parameters title and parent has no relevance and the options parameter is only used to define if the native color dialog is used or not.
