The TQColorDialog class provides a dialog widget for specifying colors.
< p > 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.
< p > The static functions provide modal color dialogs.
< p > The static < a href = "#getColor" > getColor< / a > () function shows the dialog and allows the
user to specify a color. The < a href = "#getRgba" > getRgba< / a > () function does the same but
also allows the user to specify a color with an alpha channel
(transparency) value.
< p > The user can store < a href = "#customCount" > customCount< / a > () different custom colors. The
custom colors are shared by all color dialogs, and remembered
during the execution of the program. Use < a href = "#setCustomColor" > setCustomColor< / a > () to set
the custom colors, and use < a href = "#customColor" > customColor< / a > () to get them.

< h3 class = fn > TQRgb < a name = "customColor" > < / a > TQColorDialog::customColor ( int i )< tt > [static]< / tt >
< / h3 >
Returns custom color number < em > i< / em > as a TQRgb.
< h3 class = fn > int < a name = "customCount" > < / a > TQColorDialog::customCount ()< tt > [static]< / tt >
< / h3 >
Returns the number of custom colors supported by TQColorDialog. All
color dialogs share the same custom colors.
< h3 class = fn > < a href = "ntqcolor.html" > TQColor< / a > < a name = "getColor" > < / a > TQColorDialog::getColor ( const < a href = "ntqcolor.html" > TQColor< / a > & initial = white, < a href = "tqwidget.html" > TQWidget< / a > * parent = 0, const char * name = 0 )< tt > [static]< / tt >
< / h3 >
Pops up a modal color dialog, lets the user choose a color, and
returns that color. The color is initially set to < em > initial< / em > . The
dialog is a child of < em > parent< / em > and is called < em > name< / em > . It returns
an invalid (see < a href = "ntqcolor.html#isValid" > TQColor::isValid< / a > ()) color if the user cancels the
dialog. All colors allocated by the dialog will be deallocated
before this function returns.
< p > Examples: < a href = "tutorial2-08.html#x2601" > chart/setdataform.cpp< / a > and < a href = "scribble-example.html#x909" > scribble/scribble.cpp< / a > .
< h3 class = fn > TQRgb < a name = "getRgba" > < / a > TQColorDialog::getRgba ( TQRgb initial, bool * ok = 0, < a href = "tqwidget.html" > TQWidget< / a > * parent = 0, const char * name = 0 )< tt > [static]< / tt >
< / h3 >
Pops up a modal color dialog to allow the user to choose a color
and an alpha channel (transparency) value. The color+alpha is
initially set to < em > initial< / em > . The dialog is a child of < em > parent< / em >
and called < em > name< / em > .
< p > If < em > ok< / em > is non-null, < em > *< / em > < em > ok< / em > is set to TRUE if the user clicked
OK, and to FALSE if the user clicked Cancel.
< p > If the user clicks Cancel, the < em > initial< / em > value is returned.
< h3 class = fn > void < a name = "setCustomColor" > < / a > TQColorDialog::setCustomColor ( int i, TQRgb c )< tt > [static]< / tt >
< / h3 >
Sets custom color number < em > i< / em > to the TQRgb value < em > c< / em > .
< h3 class = fn > void < a name = "setStandardColor" > < / a > TQColorDialog::setStandardColor ( int i, TQRgb c )< tt > [static]< / tt >
< / h3 >
Sets standard color number < em > i< / em > to the TQRgb value < em > c< / em > .
