|
|
|
|
|
|
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="ntqwidget.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="ntqwidget.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>.
