ILLUSTRATION OF CCOLORDIALOG

The constructor of the CColorDialog takes the initial parameter as the default color and the next parameter specifies how much the dialog is displayed. It is a modal dailog. The Modal dialogs are exhibited using the DoModal() function. The Modal dialog required to be disposed by clicking the ok or cancel button. To build a color dialog follow the steps as shown below.

1. Generate a SDI application.

2. Handle the Right button double click message for the CcolordlgView object id.

3. In response to Step 2 the event handler will be inserted in the colordlgView.cpp.

4. Generate a device context with which you can draw by using the CClientDC class.

5. Generate a color dialog object by using the CColorDialog class. In this situation dlg is the color dialog object.

6. The initial parameter RGB(255,0,0) shows that the Red is the default color.

7. The modal dialog is displayed by using the DoModal function as the dlg.DoModal()

8. We are going to choose a color from the color dialog.

9. Consequently create a variable color by using COLORREF.

10. The variable color is assigned the color by using the GetColor() function.

11. Generate a Cbrush object (mybrush) with the selected color to draw.

12. Use the selected color with the SelectObject function.

13. The SelectObject function will put into use of the new GDI object and return the present object.

14. By using the new color namely red, that is the default color, an ellipse would be drawn when the right button is double clicked.

15. Execute the project, double click the right button, select a color and click the ok button of the color dialog.

16. An ellipse would be filled with the selected color.

void CColordlgView::OnRButtonDblClk(UINT nFlags, CPoint point)

{

CClientDC dc(this);

CColorDialog dlg(RGB(255,0,0),CC_FULLOPEN);

/* RGB(255,0,0) red color, default also red color*/

dlg.DoModal();

COLORREF color = dlg.GetColor();

//color can be a var and assign value

CBrush mybrush(color);

dc.SelectObject(&mybrush);

dc.Ellipse(20,40,100,150);

}
