Changing Background Color of CEdit - Problem With Double Clicking On Texts

Author	Message
Wee Chua #1 / 6	Changing Background Color of CEdit - Problem With Double Clicking On Texts Hi. I've a multiline edit control (IDC_EDIT1) which is read-only. I tried to set the background color to white and text color to blue using the default brush with the following codes: HBRUSH CCeditDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor) { HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor); // TODO: Change any attributes of the DC here if (pWnd->GetDlgCtrlID() == IDC_EDIT1) { CRect rc; pWnd->GetClientRect(&rc); pDC->Rectangle(0, 0, rc.Width(), rc.Height ()); pDC->SetBkColor(RGB(255, 255, 255)); pDC->SetTextColor(RGB(0, 0, 255)); } // TODO: Return a different brush if the default is not desired return hbr; Quote: } Although this seems to work, every time I double click on the texts inside the edit control, problem arises. The selected texts get highlighted as expected but the rest of the contents of the edit control simply disappear. Anybody got any idea on how to fix this? Thanks.

Jeff Partc #2 / 6	Changing Background Color of CEdit - Problem With Double Clicking On Texts I suspect your call to CDC::Rectangle which fills the interior of your GetClientRect with the currently selected brush and frames it with the currently selected pen. What happens if you take that out? Why is it there in the first place? -- Jeff Partch [VC++ MVP] Quote: > Hi. I've a multiline edit control (IDC_EDIT1) which is > read-only.

Wee Chua #3 / 6	Changing Background Color of CEdit - Problem With Double Clicking On Texts The call to CDC::Rectangle was meant to fill the entire multiline edit control with the white background. If I remove it, then the problem of disappering text is gone. But then only the lines of the edit control which contain texts are painted with the white background. The rest is still in the default grey color... pls assist Quote: >-----Original Message----- >I suspect your call to CDC::Rectangle which fills the interior of your >GetClientRect with the currently selected brush and frames it with the >currently selected pen.

At a guess, GetSysColorBrush(COLOR_WINDOW) is what you're after. -- Jeff Partch [VC++ MVP]

Wee Chua #5 / 6	Changing Background Color of CEdit - Problem With Double Clicking On Texts Thanks Jeff. I've tried out GetSysColorBrush (COLOR_WINDOW). But it seems that the entire window (including the parent dialog) is painted with white background. How can I paint only the entire edit control without altering the color of the dialog?

Nobod #6 / 6	Changing Background Color of CEdit - Problem With Double Clicking On Texts The text does not dissaper, but I guess since the highlighted text have the same color as the highlighted background, you can see them. I don't know if there is control to set the 'highlighted' color for edit control (what you did below was setting color for normal (non-highlighted) text). You might want to do your research there.
