class TGColorPick: public TGFrame, public TGWidget


TGColorPalette, TGColorPick and TGColorDialog.

The TGColorPalette is a widget showing an matrix of color cells. The
colors can be set and selected.

The TGColorPick is a widget which allows a color to be picked from
HLS space. It consists of two elements: a color map window from
where the user can select the hue and saturation level of a color,
and a slider to select color's lightness.

Selecting a color in these two widgets will generate the event:
kC_COLORSEL, kCOL_CLICK, widget id, 0.
and the signal:
ColorSelected(Pixel_t color)

The TGColorDialog presents a full featured color selection dialog.
It uses 2 TGColorPalette's and the TGColorPick widgets.

Function documentation

TGColorPick(const TGWindow* p = 0, Int_t w = 1, Int_t h = 1, Int_t id = -1)
 TGColorPick constructor.
 TGColorPick is a widget which allows a color to be picked from HLS space.
 It consists of two elements: a color map window from where the user can
 select the hue and saturation level of a color, and a slider to select
 color's lightness.
~TGColorPick()
 TGColorPick destructor.
Bool_t HandleButton(Event_t* event)
 Handle mouse button events in color pick widget.
Bool_t HandleMotion(Event_t* event)
 Handle mouse motion events in color pick widget.
void CreateImages()
 Create colormap and color slider images.
void AllocColors()
 Try to allocate first a palette of 64 colors. Used by the dithered
 version of the color maps.
void FreeColors()
 Free allocated colors.
void CreateDitheredImage(Pixmap_t image, Int_t which)
 Create a dithered version of the color map and lightness images for
 display modes with reduced number of colors. The Floyd-Steinberg error
 diffusion dithering algorithm is used.
 This routine is called in PseudoColor modes only.
void InitImages()
 Initialize color palette and slider images.
void SetSliderColor()
 Set slider colors.
void SetColor(Pixel_t color)
 Position the slider cursor on right color position.
void UpdateCurrentColor()
 Assign the current cursor position as currently selected color.
void DoRedraw()
 Redraw the color pick widget.
void SetHScursor(Int_t x, Int_t y)
 Set hue / saturation cursor position.
void SetLcursor(Int_t z)
 Set lightness slider cursor position.
void DrawHScursor(Int_t onoff)
 Draw hue / saturation cursor
void DrawLcursor(Int_t onoff)
 Draw lightness slider cursor
Pixel_t GetCurrentColor() const
void ColorSelected(Pixel_t col = 0)
{ Emit("ColorSelected(Pixel_t)", col ? col : GetCurrentColor()); }
