1681 | \class QColorDialog |
1682 | \brief The QColorDialog class provides a dialog widget for specifying colors. |
1683 | |
1684 | \ingroup standard-dialogs |
1685 | |
1686 | The color dialog's function is to allow users to choose colors. |
1687 | For example, you might use this in a drawing program to allow the |
1688 | user to set the brush color. |
1689 | |
1690 | The static functions provide modal color dialogs. |
1691 | \omit |
1692 | If you require a modeless dialog, use the QColorDialog constructor. |
1693 | \endomit |
1694 | |
1695 | The static getColor() function shows the dialog, and allows the user to |
1696 | specify a color. This function can also be used to let users choose a |
1697 | color with a level of transparency: pass the ShowAlphaChannel option as |
1698 | an additional argument. |
1699 | |
1700 | The user can store customCount() different custom colors. The |
1701 | custom colors are shared by all color dialogs, and remembered |
1702 | during the execution of the program. Use setCustomColor() to set |
1703 | the custom colors, and use customColor() to get them. |
1704 | |
1705 | The \l{dialogs/standarddialogs}{Standard Dialogs} example shows |
1706 | how to use QColorDialog as well as other built-in Qt dialogs. |
1707 | |
