GridCtrl:

grid.GetRow(22).Bg(Red);


I've used it at runtime, not in the constructor, and I discovered that was necessary to add the instruction grid.Repaint() to see the new color. I guess this is normal.

I think it has to be change. Bg and similar functions should refresh the grid. Calling Repaint is not optimal as it recalculate rows/columns (if needed) positions and repaint the whole content.
I used Bg mainly in callbacks where calling refresh is not necessary as outer functions that call callbacks do this.
Anyway it will be fixed before final release.

PS: It's better to call RefreshRow(int n) instead of Repaint

Hello,

I used

grid.GetRow(x).Bg(Red);

to set red the color of some row of a gridctrl where the rows are white and blu depending of their parity
( grid.ColorRows().EvenColor(SColorText, Blend(SColorMark, SColorPaper, 220)); ) .
The red color depend of the value in a coloumn. So in some case the cell need to be set at its default color.
How to remove the red color and leave the default color?

Thanks,
Luigi

ArrayCtrl: set background color to all cells of row Wink

Anyway, it is as well possible and often more practical to use AttrText.

Hello Mirek,

thank you for the reply. I am afraid you have answered to an old question Smile.
The newest question regarded GridCtrl and how to remove at runtime a previously assigned color so that the default is applied. Perhaps for it I must wait Daniel.

Luigi

Ah I see. That is why I do not think it is a good idea to 'recycle' existing threads Smile

Hi Forlano,

I had to do something approaching and I used a gridDisplay for it:

class BgColorGridDisplay : public GridDisplay
{
	private:
		Color _bg; //(140, 140, 140);
	public:
	
	BgColorGridDisplay(const Color color)
	: _bg(color)
	{}
	 
	virtual void Paint(Draw &w, int x, int y, int cx, int cy, const Value &val, dword style,
			           Color &fg, Color &bg, Font &fnt, bool found = false, int fs = 0, int fe = 0)
   {
       if (found)
       {
	       GridDisplay::Paint(w,x,y,cx,cy,val,style,fg,bg,fnt,found,fs,fe);
       }
       else
       {
    	   GridDisplay::Paint(w,x,y,cx,cy,val,style,fg,_bg,fnt,found,fs,fe);
       }
   }
};


You can either remove the display to restore original color or enhance it to keep it form overwriting original color.

tabGrid.dataGrid.AddColumn("ColName", 110).SetDisplay( greyBgDisplay )


I use it in order to change bkgnd colour of only some columns while others are changed on cell value just like you.
