Description

m_bIsMyPalette

TRUE if the color selection dialog box uses its own color palette, or FALSE if the dialog box uses a palette that is specified in the CMFCColorDialog constructor.

m_bPickerMode

TRUE while the user is selecting a color from the selection dialog box; otherwise, FALSE.

m_btnColorSelect

The color button that the user has selected.

The currently selected color.

m_hcurPicker

The cursor that is used to pick a color.

m_NewColor

The prospective selected color, which can be permanently selected or reverted to the original color.

m_pColourSheetOne

A pointer to the first property page of the color selection property sheet.

m_pColourSheetTwo

A pointer to the second property page of the color selection property sheet.

The color selection dialog box is displayed as a property sheet with two pages. On the first page, you select a standard color from the system palette; on the second page, you select a custom color.

You can construct a CMFCColorDialog object on the stack and then call DoModal, passing the initial color as a parameter to the CMFCColorDialog constructor. The color selection dialog box then creates several CMFCColorPickerCtrl Class objects to handle each color palette.

The following example demonstrates how to configure a color dialog by using various methods in the CMFCColorDialog class. The example shows how to set the current and the new colors of the dialog, and how to set the red, green, and blue components of a selected color on the two property pages of the color dialog. This example is part of the New Controls sample.


	// COLORREF m_Color
	CMFCColorDialog dlg(m_Color, 0, this);
	dlg.SetCurrentColor(RGB(0,255,0));
	dlg.SetNewColor(RGB(0,0,255));
	// set the red, green, and blue components of a selected
	// color on the two property pages of the color dialog
	dlg.SetPageOne(255,0,0);
	dlg.SetPageTwo(0,255,0);
