RequestColor:Int32 red:Int32=255, green:Int32=255, blue:Int32=255

Parameter	Mode	Type	Default	Description
red	In	Int32	255	Red the sliders start at, 0 to 255. Defaults to 255.
green	In	Int32	255	Green the sliders start at, 0 to 255. Defaults to 255.
blue	In	Int32	255	Blue the sliders start at, 0 to 255. Defaults to 255.

Returns: 1 if the user pressed OK, 0 if the dialog was cancelled.

Description

Opens a color picker with three sliders and waits until the user presses OK or Cancel. Read the picked color with RequestedRed, RequestedGreen and RequestedBlue. While the picker is open nothing else in the program window reacts.

Differences

• The picker is drawn by the runtime inside the program's active window (the window of Graphics where there is none) and is simpler than the Windows color dialog: three sliders and a preview, no palette and no custom colors. Return confirms and Escape cancels; the mouse counts in that window only.

Examples

Graphics 480, 300, 32, 2
win   = CreateWindow("Pick", 20, 20, 240, 140, Desktop(), 3)
swatch = CreatePanel(20, 20, 100, 60, win)
If RequestColor(40, 120, 200) Then
	SetPanelColor swatch, RequestedRed(), RequestedGreen(), RequestedBlue()
EndIf
Repeat
Until WaitEvent() = $803
