Inheritance diagram for GuiColorPickerCtrl:

Detailed Description

This control draws a box containing a color specified by mPickColor, in a way according to one of the PickMode enum's, stored as mDisplayMode.

The color the box represents is stored as mBaseColour (for pPallete, pBlendColorRange), whilst the color chosen by the box is stored as mPickColor.

Whenever the control is clicked, it will do one of many things :

If its in pPallete mode, execute the regular "command"
If its in pBlendColorRange mode, update the selector position. The position will be re-read upon the next render. In addition, a cross will be drawn where the color has been selected from. As with 1, "command" will be executed.
If its in pHorizColorRange or pVertColorRange mode, it will function in a similar manner to 2, but the selector will resemble a horizontal or vertical bar.
If its in pHorizAlphaRange or pVertAlphaRange mode, it will also function the same way as 3
If its in pDropperBackground mode, nothing will happen

Colours are drawn in different ways according to mDisplayMode:

With pPallete, a box with a blank color, mBaseColor is drawn.
With pHorizColorRange, a horizontal box with colors blending in the range, mColorRange.
With pVertColorRange, a vertical box with colors blending in the range, mColorRange.
With pBlendColorRange, a box, the bottom colors being black, but the top left being white, and the top right being mBaseColor.
With pHorizAlphaRange, a horizontal box with black blending with an alpha from 0 to 255
With pVertAlphaRange, a vertical box with black blending with an apha from 0 to 255
With pDropperBackground, nothing is drawn

Core Variables

ColorF mPickColor

Color that has been picked from control.

ColorF mBaseColor

Colour we display (in case of pallet and blend mode).

PickMode mDisplayMode

Current color display mode of the selector.

Point2I mSelectorPos

Current position of the selector.

bool mPositionChanged

Current position has changed since last render?

bool mMouseOver

Mouse is over?

bool mMouseDown

Mouse button down?

bool mActionOnMove

Perform onAction() when position has changed?

S32 mSelectorGap

The half-way "gap" between the selector pos and where the selector is allowed to draw.

GFXStateBlockRef mStateBlock

static ColorI mColorRange [9]

Color range for pHorizColorRange and pVertColorRange.

Public Types

pPallet = 0

We just have a solid color; We just act like a pallet.

pHorizColorRange

We have a range of base colors going horizontally.

pVertColorRange

We have a range of base colors going vertically.

pHorizColorBrightnessRange

HorizColorRange with brightness.

pVertColorBrightnessRange

VertColorRange with brightness.

pBlendColorRange

We have a box which shows a range in brightness of the color.

pHorizAlphaRange

We have a box which shows a range in alpha going horizontally.

pVertAlphaRange

We have a box which shows a range in alpha going vertically.

pDropperBackground

The control does not draw anything; Only does something when you click, or move the mouse (when active).

sHorizontal = 0

Horizontal selector with small gap.

sVertical

Vertical selector with small gap.

DECLARE_CONOBJECT (GuiColorPickerCtrl)

GuiColorPickerCtrl ()

void onRender (Point2I offset, const RectI &updateRect)

Called when this control is to render itself.

Color Value Functions

NOTE: setValue only sets baseColor, since setting pickColor wouldn't be useful

void setValue (ColorF &value)

ColorF getValue ()

NOTE: getValue() returns baseColor if pallet (since pallet controls can't "pick" colours themselves).

const char * getScriptValue ()

Returns the value of the variable bound to this object.

void setScriptValue (const char *value)

Sets the value of the variable bound to this object.

void updateColor ()

Selector Functions

void setSelectorPos (const Point2I &pos)

Set new pos (in local coords).
