Brush
Posted on 2000-03-18
Experts:
I have a problem:
I create a brush in OnCtlColor() and return it later.This will make my control turn different color.
For example:
HBRUSH CMydialog::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
CBrush mybrush;
mybrush.CreateSolidBrush (RGB( 255, 0, 0 ));
if ( nCtlColor == CTLCOLOR_BTN )
{
pDC->SetBkColor(RGB(255,0,0));
pDC->SetTextColor(RGB(0,0,0));
return mybrush;
}
My confusion is since I create mybrush in the function above and mybrush should get destructed after return.I think the mybrush should die.How the system can use it to draw control color?
But in face it works!
And how about declare the brush in the if statement? Does it make difference?
Many thx.
