Row BackColor in inactive BROWSE control

[mol]

Hi guys!
We have function CellNavigationColor which can set colors of GRID control.
But, anybody knows the way to change active row colors in BROWSE, especially when focus is out of this control (in this situation active row is backlighted by default window backgroud color, default light grey)?

I want to refresh this topic.

Hi Mol,

Might this example from my BROWSE be helpful?

Code: Select all

// In my Main.PRG:
public bkItemType := ;
	{ || iif( alltrim( Items->Type_Item ) == "Short" ;
			, {255,215,215} ;
	,	 iif( alltrim( Items->Type_Item ) == "Medium" ;
			, {230,225,130} ;
	,	 iif( alltrim( Items->Type_Item ) == "Long" ;
			, {180,220,235} ;

// In my Browse's DynamicBackColor:
{ bkItemType, bkItemType, bkItemType, bkItemType, bkItemType, bkItemType, bkItemType }

Kind regards,

Red2

I don't want to use DynamicBackColor.
I want to change row highlight color when Browse is not active - in this situation selected row background is grey - on almost LCD monitors it's hard to see the difference between white

Hi Mol
You can change the backcolor and current row is normal. I can not figure how to change current row.

DEFINE BROWSE brwItems

BACKCOLOR {200,200,200} // { 255, 255, 255}
FONTCOLOR { 0, 0, 0 }

I want to change color in the state when browse is inactive

Marku, nie jestem biegły w C i nie pomogę w zmianie koloru wybranego wiersza, ale aby zrobić go bardziej czytelnym, może spróbuj w inną mańkę, np. zmienić kolor tła Browse przy utracie fokusa i przywrócić kolor tła przy uzyskaniu fokusa:
ON GOTFOCUS ( This.BackColor := {255,255,255} );
ON LOSTFOCUS ( This.BackColor := {215,215,215} );

Nice idea!
I''ll try it
Dzięki, Edward!

I found solution, but it's written in basic.
I don't know how to adapt it to BROWSE control.
Maybe someone is able to do it?
