CTreeCtrl get individual item font ?

Maximilien

I'm setting a CTreeCtrl item item font to Italic by handling the NM_CUSTOMDRAW message and setting the font with SelectObject. This is working.

void MyTree::OnNMCustomdraw(NMHDR *pNMHDR, LRESULT *pResult)
{
NMTVCUSTOMDRAW *itemToDraw = reinterpret_cast<NMTVCUSTOMDRAW*>>(pNMHDR);

switch (itemToDraw->nmcd.dwDrawStage)
{
case CDDS\_PREPAINT:
	\*pResult = CDRF\_NOTIFYITEMDRAW;
	return;
case CDDS\_ITEMPREPAINT:
{
	HTREEITEM item = reinterpret\_cast<HTREEITEM>(itemToDraw->nmcd.dwItemSpec);

	if (!m\_IsItalicFontCreated) //Create once the italic font
	{
		CFont\* currentFont = GetFont();
		LOGFONT logfont;
		currentFont->GetLogFont(&logfont);
		logfont.lfItalic = TRUE;
		m\_ItalicFont.CreateFontIndirect(&logfont);
		m\_IsItalicFontCreated = true;
	}

	if (m\_IsItalicFontCreated)
	{
		::SelectObject(itemToDraw->nmcd.hdc, m\_ItalicFont);
		\*pResult = CDRF\_NEWFONT;
	}
}
return;
}

\*pResult = 0;

}

But at some point I need to check an item current font; to see if a tree item is in italic. The CTreeCtrl's item data (CTreeCtrl::SetItemData) is already used to hold data for each item. Is it possible to do it ? I can't see in the documentation anything I can use. There is a lItemlParam in the NMCUSTOMDRAW struct, I'm not certain if I could use this to some some simple data ? or even if it is persistent. Any suggestions ? Thanks.

You could implement the method in your MyTree class that would return true if italic font was created. Something like

bool MyTree::IsItalicFontCreated()
{
return m_IsItalicFontCreated;
}

You could extend your data adding the font type (create a struct containing all the necessary data and set the pointer to the struct instance as an ItemData)

That only tells me the font is created, but not if it was set to one particular tree item.

Yes, I'm looking into that. Thanks. :thumbsup:
