Hi!!

If I got the following codes,
how to increase the width of a popup menu ?

---------------------------------------------------------------------------------------------

LRESULT CChildFrame::OnExtMenuPrepare(WPARAM wParam, LPARAM lParam)
{
CExtPopupMenuWnd::MsgPrepareMenuData_t * pData =
reinterpret_cast
< CExtPopupMenuWnd::MsgPrepareMenuData_t * >
( wParam );
ASSERT( pData != NULL );
CExtPopupMenuWnd * pPopup = pData->m_pPopup;
ASSERT( pPopup != NULL );


// Here...I can, of course, use pPopup (which points a popup menu)
// I want to increase and extend its width here...


Any comment would be very very welcome.
Thanks in advance.

You can insert one or more space characters at the beginning/end of a menu item. You can also add the left area to the menu as it is demonstrated in the ProfUIS_Controls sample. Please let us know more details about this? Why do you need a larger menu than that provided by the currently installed paint manager by default?

As it is a dynamic popup menu, I don’t know the length of some menu items.
If the length of a menu item is short enough, it is no problem.
But what-if it is long...
At the moment, around 10 characters can be shown.
The remaining characters are shown like dot dot dot (...) or nothing being shown.
So I just need to increase its width.

Thanks.

We guess the following line is missing in your CChildFrame::OnExtMenuPrepare() method:

pData->m_bMenuChanged = true;

This causes that the popup menu’s layout is not recomputed after you have initialized it dynamically.
