How do you set cell attributes of a virtual wxListCtrl ? Topic is solved

[katuday]

I have a virtual wxListCtrl

Code: Select all

class MyList : public wxListCtrl
….
virtual wxString OnGetItemText(long item, long column) const
{
// 
}

m_mylist = new MyList(this, ID_MYLIST, wxDefaultPosition, wxSize(-1, -1), wxLC_REPORT | wxLC_NO_HEADER | wxLC_VIRTUAL | wxLC_SINGLE_SEL | wxLC_HRULES | wxLC_VRULES );

How do I set the font, background color etc of the cell attributes?

There are a few more virtual methods you can override:

Thanks for the lead.
So I created an attributes object

Code: Select all

wxListItemAttr m_attr;

Set the attributes in the constructor of my model as

Code: Select all

m_attr.SetFont(wxFontInfo(12).FaceName("Tahoma"));

and implemented OnGetItemAttr as

Code: Select all

wxListItemAttr* OnGetItemAttr(long item) const
{
	return (wxListItemAttr *)&m_attr;
}

But this method is not being called at all. But my OnGetItemText is getting called as expected.
What did I miss?

I am on WIndows 10. Visual Studio 2017

It seems that under Windows OnGetItemAttr is not called, only OnGetItemColumnAttr.

I guess that's something that should be mentioned in the documentation.
