hi,all
when i use the SWT.FULL_SELECTION, something was puzzled me 。

I create the JFace TreeView like this:

new TreeViewer(parent, SWT.FULL_SELECTION).

then i set the CustomLabelProvider.
the CustomLabelProvider declare like this :

>public class CustomLabelProvider implements ITableLabelProvider
,ITableColorProvider

as you see ,i implements the ITableColorProvider 。

> public Color getBackground(Object arg0, int arg1) {
> Color color = new Color(null, 255, 255, 255);//color is black
> return color;
> }

when i do that ,i thought the backgroundColor of all columns shoud be black.

but the fact is that :

columnindex ==0 the backgroundColor is black. (right )
columnindex >=0 (1.2.3...........) the backgroundColor is not black,it
seems that the backgroundColor is not setted
or reset some other color.

When i change the treeview style,for exmaple :
new TreeViewer(parent).// i use the default style

the everything is right ,the backgroundColor of all columns is
black。。。。。。

when i use “SWT.FULL_SELECTION”, what had happend ?

who will help me ?

Thank you very much !

from kevin

Please note that you are leaking colors with the implementation you have
shown.

What platform are you running on and what version of Eclipse are you using?

The following works for me on Windows XP. It is straight SWT code (no
JFace). Does it work for you?

public static void main (String [] args) {
Display display = new Display ();
final Color red = display.getSystemColor(SWT.COLOR_RED);
final Color green = display.getSystemColor(SWT.COLOR_GREEN);
final Color blue = display.getSystemColor(SWT.COLOR_BLUE);
Shell shell = new Shell (display);
shell.setLayout(new FillLayout());
Tree tree = new Tree(shell, SWT.FULL_SELECTION);
tree.setHeaderVisible(true);
TreeColumn column0 = new TreeColumn(tree, SWT.LEFT);
TreeColumn column1 = new TreeColumn(tree, SWT.RIGHT);
TreeColumn column2 = new TreeColumn(tree, SWT.CENTER);
for (int i = 0; i < 4; i++) {
TreeItem item = new TreeItem(tree, SWT.NONE);
item.setText(new String[] {"qqqqq", "yyyy", "pppppppp"});
item.setBackground(0, red);
item.setBackground(1, green);
item.setBackground(2, blue);
for (int j = 0; j < 4; j++) {
TreeItem subItem = new TreeItem(item, SWT.NONE);
subItem.setText(new String[] {"qqqqq", "yyyy",
"pppppppp"});
subItem.setBackground(0, green);
subItem.setBackground(1, blue);
subItem.setBackground(2, red);
}
}
column0.pack();
column1.pack();
column2.pack();
shell.pack();
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}

hi,Veronika Irvine
Thank you for your help !

this is my env:
Eclipse version: 3.1.1
OS: windows 2000 server

I had run your code ,but the setting of the color does not work for me.
(you could see the picture in the attachment)

when i create the tree not use SWT.FULL_SELECTION ,
the setting of color is right.

Is some constraint for the color setting?
Is version of my eclipse or OS wrong?

thank you !

from kevin
