How to fix Static contol width at run time?

Le rner

Hi all, on dialog box i have a static contol i want to fit its width according to its text when dialog box is open or text change . i use this but the control width is set less than text width..

// get the text dimensions
CString strText;
m_label.GetWindowText(strText);
CClientDC dc(this);
CFont* pFont = GetFont();
CFont* pOldFont = (CFont*)dc.SelectObject(pFont);
CSize sizeText = dc.GetTextExtent(strText);
dc.SelectObject(pOldFont);

// get the text area (presume left-alligned text).
CRect rcText;
m\_label.GetWindowRect(rcText);

CRect dlg\_stc=rcText;
this->ScreenToClient(dlg\_stc);

rcText = dlg\_stc;

rcText.right = min(rcText.right, sizeText.cx);


CRect new\_rect=rcText;
m\_label.MoveWindow(new\_rect);

can anybody help me to do this. thanks.

I have had a similar issue in the past and used the GetTextExtentPoint32() function. I also found it necessary to add the size of a couple of extra characters as the calculation seems very precise.

Use the best guess

this also gives the same width.

try this for the above statement,

rcText.right = rcText.left + sizeText.cx

and try to avoid using unwanted temporary variables, you can simply have as below,

CRect rcLabel;
m_label.GetWindowRect(rcLabel); //get screen co-ordinate for static ctrl
rcLabel.right = rcLabel.left + sizeText.cx; //increase/decrease the rect width
ScreenToClient(rcLabel); // convert screen co-ordinate to client co-ordinate
m_label.MoveWindow(rcLabel); //move the static ctrl to new position

Do your Duty and Don't Worry about the Result
