The _COLORCHOOSERDIALOG function displays a standard color picker dialog box. It returns a 32-bit RGBA color with the alpha channel set to &HFF (255). A zero is returned if the user cancelled.


Syntax

color32bpp~& = _COLORCHOOSERDIALOG([title$][, defaultRGB~&])


Parameters

  • title$ is the dialog box title
  • defaultRGB~& is the default 32-bit RGB color that is pre-selected


Description

  • title$ accepts an empty string ("") in which case system defaults are used
  • The dialog box automatically becomes a modal window if the application window is visible
  • defaultRGB~& may be ignored on some platforms


Availability

  • QB64-PE v3.4.0 and up


Examples

Example
Color selection
mycolor~& = _COLORCHOOSERDIALOG("Select a color", _RGB32(0, 255, 255))
IF mycolor~& <> 0 THEN _MESSAGEBOX "Information", "You selected " + HEX$(mycolor~&)
