Hi,
U++ 1713.
If I add values in an ArrayCtrl, using AttrText() for change the default font, I get the followings problems:
1) The value in the cell will be Null when edit it;
2) After end edit the cell, the font of this cell will be again the default font.
If I add values without AttrText() the editors working as well.
Following an short demo code:
#include <CtrlLib/CtrlLib.h>
using namespace Upp;
GUI_APP_MAIN
{
ArrayCtrl a;
Array<EditString> es;
a.AddColumn("Text1").Edit(es.Add().SetFont(Courier(11)));
a.AddColumn("Text2").Edit(es.Add().SetFont(Courier(11)));
for(int i = 0; i < 10; i++)
//a.Add(AttrText(AsString(i)).SetFont(Courier(11)),
// AttrText(AsString(i*-1)).SetFont(Courier(11))
//);
a.Add(AsString(i),
AsString(i*-1)
);
a.SetLineCy(Draw::GetStdFontCy() + 4);
TopWindow app;
app.Add(a.SizePos());
app.Sizeable();
app.Run();
}
bye
Mauro Bottizzo.

Yes, this a feature, not a bug...
AttrText is sort of special hack if you need to display something in color/font. It is special a special type of Value and cannot be edited.
To achieve what you need, you have to use proper Display to change the appearance of cell instead of AttrText.
