DESCRIPTION

22       The QColorDialog class provides a dialog widget for specifying colors.
23
24       The color dialog's function is to allow users to choose colors. For
25       example, you might use this in a drawing program to allow the user to
26       set the brush color.
27
28       The static functions provide modal color dialogs.
29
30       The static getColor() function shows the dialog and allows the user to
31       specify a color. The getRgba() function does the same but also allows
32       the user to specify a color with an alpha channel (transparency) value.
33
34       The user can store customCount() different custom colors. The custom
35       colors are shared by all color dialogs, and remembered during the
36       execution of the program. Use setCustomColor() to set the custom
37       colors, and use customColor() to get them.

MEMBER FUNCTION DOCUMENTATION

QRgb QColorDialog::customColor ( int i ) [static]
48       Returns custom color number i as a QRgb.
49

int QColorDialog::customCount () [static]
51       Returns the number of custom colors supported by QColorDialog. All
52       color dialogs share the same custom colors.
53

QColor QColorDialog::getColor ( const QColor & initial = white, QWidget *
55       parent = 0, const char * name = 0 ) [static]
56       Pops up a modal color dialog, lets the user choose a color, and returns
57       that color. The color is initially set to initial. The dialog is a
58       child of parent and is called name. It returns an invalid (see
59       QColor::isValid()) color if the user cancels the dialog. All colors
60       allocated by the dialog will be deallocated before this function
61       returns.
62
63       Examples:
64

QRgb QColorDialog::getRgba ( QRgb initial, bool * ok = 0, QWidget * parent =
66       0, const char * name = 0 ) [static]
67       Pops up a modal color dialog to allow the user to choose a color and an
68       alpha channel (transparency) value. The color+alpha is initially set to
69       initial. The dialog is a child of parent and called name.
70
71       If ok is non-null, *ok is set to TRUE if the user clicked OK, and to
72       FALSE if the user clicked Cancel.
73
74       If the user clicks Cancel, the initial value is returned.
75

void QColorDialog::setCustomColor ( int i, QRgb c ) [static]
77       Sets custom color number i to the QRgb value c.
78

void QColorDialog::setStandardColor ( int i, QRgb c ) [static]
80       Sets standard color number i to the QRgb value c.
