Thread: ListView problem

Okay when I call the ListView_GetSubItemRect() it returns the co-ordinates, however, my co-ords are not correct. Using the RECT that is filled by the ListView_GetSubItemRect() call I am creating an editbox (supposed to be created at the location and be the size of the subitem I used during that call) for user input. However, when the editbox is created it is created in a manner that it is about 10 - 15px above where it should be (for location) and if the subitem happens to be (0,0) in the ListView then it's length is created matching the length of the ListView, however, if the item is (0,1) or otherwise, then it is created with the right length to match the column.

Can anyone help me with this issue?

Here is some code:

Code:

// get ready for user input
err = ListView_GetSubItemRect(expHwnds.hLV_Wnd, 0, 0, LVIR_BOUNDS, &rect);
if( err == 0 )
{
	sprintf(error, "Unable to get dimensions of first item. %u", GetLastError());
	MessageBox(NULL, error, "Error", MB_ICONEXCLAMATION);
	return(-1);
}
else
{
	expHwnds.hEdit = CreateWindow("EDIT", "MM/DD/YYYY", WS_CHILD | WS_BORDER | WS_VISIBLE | ES_MULTILINE | ES_WANTRETURN, rect.left, rect.top, rect.right - rect.left, rect.bottom - rect.top, hwnd, NULL, g_hInst, NULL);
	if( expHwnds.hEdit == NULL )
	{
		sprintf(error, "Unable to initialize user input for Expense module. (Error 0027; %u)", GetLastError());
		MessageBox(NULL, error, "Error", MB_ICONEXCLAMATION);
		return(-1);
	}
}

I'm not sure exactly why this is happening. Probably something very simple and stupid (maybe I should try sleep to remedy my problems? lol let me know, maybe that would be a solution!)

Assumably, ListView_GetSubItemRect is returning a rectangle that is relative to its client rectangle. However, you are positioning the edit control relative to the parent window. You need to take into account the offset from the parent client rectangle to the list-view client rectangle.

As a simpler alternative have you considered the LVS_EDITLABELS style?

P.S. Very wide code makes your post and your code hard to read. Consider breaking up lines that are too long to be viewed without scrolling.

Yes I have created the ListView using the LVS_EDITLABELS style, however, that style hinders your access to actually edit the information in the ListView. You can only edit the first item, and I want the entire ListView editable.

Thanks for the help though, now that I fixed the relativity of the RECT being returned, I was able to get it in the right location.
