.SH DESCRIPTION
|
|
The QPalette class contains color groups for each widget state.
|
|
.PP
|
|
A palette consists of three color groups: \fIactive\fR, \fIdisabled\fR, and \fIinactive\fR. All widgets contain a palette, and all widgets in TQt use their palette to draw themselves. This makes the user interface easily configurable and easier to keep consistent.
|
|
.PP
|
|
If you create a new widget we strongly recommend that you use the colors in the palette rather than hard-coding specific colors.
|
|
.PP
|
|
The color groups:
|
|
.TP
|
|
The active() group is used for the window that has keyboard focus.
|
|
.TP
|
|
The inactive() group is used for other windows.
|
|
.TP
|
|
The disabled() group is used for widgets (not windows) that are disabled for some reason.
|
|
.PP
|
|
Both active and inactive windows can contain disabled widgets. (Disabled widgets are often called \fIinaccessible\fR or \fIgrayed out\fR.)
|
|
.PP
|
|
In Motif style, active() and inactive() look the same. In Windows 2000 style and Macintosh Platinum style, the two styles look slightly different.
|
|
.PP
|
|
There are setActive(), setInactive(), and setDisabled() functions to modify the palette.
|
|
.PP
|
|
Colors and brushes can be set for particular roles in any of a palette's color groups with setColor() and setBrush().
|
|
.PP
|
|
You can copy a palette using the copy constructor and test to see if two palettes are \fIidentical\fR using isCopyOf().
|
|
.PP
|
|

.SH MEMBER FUNCTION DOCUMENTATION
|
|
.SH "QPalette::QPalette ()"
|
|
Constructs a palette that consists of color groups with only black colors.
|
|
.SH "QPalette::QPalette ( const TQColor & button )"
|
|
\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
|
|
.PP
|
|
Constructs a palette from the \fIbutton\fR color. The other colors are automatically calculated, based on this color. Background will be the button color as well.
|
|
.SH "QPalette::QPalette ( const TQColor & button, const TQColor & background )"
|
|
Constructs a palette from a \fIbutton\fR color and a \fIbackground\fR. The other colors are automatically calculated, based on these colors.
|
|
.SH "QPalette::QPalette ( const TQColorGroup & active, const TQColorGroup & disabled, const TQColorGroup & inactive )"
|
|
Constructs a palette that consists of the three color groups \fIactive\fR, \fIdisabled\fR and \fIinactive\fR. See the Detailed Description for definitions of the color groups and TQColorGroup::ColorRole for definitions of each color role in the three groups.
|
|
.PP
|
|
See also TQColorGroup and TQColorGroup::ColorRole.
|
|
.SH "QPalette::QPalette ( const QPalette & p )"
|
|
Constructs a copy of \fIp\fR.
|
|
.PP
|
|
This constructor is fast (it uses copy-on-write).
|
|
.SH "QPalette::~QPalette ()"
|
|
Destroys the palette.
|
|
.SH "const TQColorGroup & QPalette::active () const"
|
|
Returns the active color group of this palette.
|
|
.PP
|
|
See also TQColorGroup, setActive(), inactive(), and disabled().
|
|
.PP
|
|
Examples:
|
|
.)l themes/metal.cpp and themes/wood.cpp.
|
|
.SH "const TQBrush & QPalette::brush ( ColorGroup gr, TQColorGroup::ColorRole r ) const"
|
|
Returns the brush in color group \fIgr\fR, used for color role \fIr\fR.
|
|
.PP
|
|
See also color(), setBrush(), and TQColorGroup::ColorRole.
|
|
.SH "const TQColor & QPalette::color ( ColorGroup gr, TQColorGroup::ColorRole r ) const"
|
|
Returns the color in color group \fIgr\fR, used for color role \fIr\fR.
|
|
.PP
|
|
See also brush(), setColor(), and TQColorGroup::ColorRole.
|
|
.SH "QPalette QPalette::copy () const"
|
|
Returns a deep copy of this palette.
|
|
.PP
|
|
\fBWarning:\fR This is slower than the copy constructor and assignment operator and offers no benefits.
|
|
.SH "const TQColorGroup & QPalette::disabled () const"
|
|
Returns the disabled color group of this palette.
|
|
.PP
|
|
See also TQColorGroup, setDisabled(), active(), and inactive().
|
|
.PP
|
|
Examples:
|
|
.)l themes/metal.cpp and themes/wood.cpp.
|
|
.SH "const TQColorGroup & QPalette::inactive () const"
|
|
Returns the inactive color group of this palette.
|
|
.PP
|
|
See also TQColorGroup, setInactive(), active(), and disabled().
|
|
.SH "bool QPalette::isCopyOf ( const QPalette & p )"
|
|
Returns TRUE if this palette and \fIp\fR are copies of each other, i.e. one of them was created as a copy of the other and neither was subsequently modified; otherwise returns FALSE. This is much stricter than equality.
|
|
.PP
|
|
See also operator=() and operator==().
|
|
.SH "bool QPalette::operator!= ( const QPalette & p ) const"
|
|
Returns TRUE (slowly) if this palette is different from \fIp\fR; otherwise returns FALSE (usually quickly).
|
|
.SH "QPalette & QPalette::operator= ( const QPalette & p )"
|
|
Assigns \fIp\fR to this palette and returns a reference to this palette.
|
|
.PP
|
|
This is fast (it uses copy-on-write).
|
|
.PP
|
|
See also copy().
|
|
.SH "bool QPalette::operator== ( const QPalette & p ) const"
|
|
Returns TRUE (usually quickly) if this palette is equal to \fIp\fR; otherwise returns FALSE (slowly).
|
|
.SH "int QPalette::serialNumber () const"
|
|
Returns a number that uniquely identifies this QPalette object. The serial number is intended for caching. Its value may not be used for anything other than equality testing.
|
|
.PP
|
|
Note that QPalette uses copy-on-write, and the serial number changes during the lazy copy operation (detach()), not during a shallow copy (copy constructor or assignment).
|
|
.PP
|
|
See also QPixmap, QPixmapCache, and TQCache.
|
|
.SH "void QPalette::setActive ( const TQColorGroup & g )"
|
|
Sets the Active color group to \fIg\fR.
|
|
.PP
|
|
See also active(), setDisabled(), setInactive(), and TQColorGroup.
|
|
.SH "void QPalette::setBrush ( ColorGroup gr, TQColorGroup::ColorRole r, const TQBrush & b )"
|
|
Sets the brush in color group \fIgr\fR, used for color role \fIr\fR, to \fIb\fR.
|
|
.PP
|
|
See also brush(), setColor(), and TQColorGroup::ColorRole.
|
|
