Hi everyone
I've been taking a look at this grid and made the following very simple
example:
package test;
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.nebula.widgets.grid.Grid;
import org.eclipse.swt.nebula.widgets.grid.GridColumn;
import org.eclipse.swt.nebula.widgets.grid.GridItem;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
public class Test {
public static void main (String [] args)
{
Display display = new Display ();
Shell shell = new Shell (display);
shell.setLayout(new FillLayout());
Grid grid = new Grid(shell,SWT.BORDER | SWT.V_SCROLL | SWT.H_SCROLL);
grid.setHeaderVisible(true);
GridColumn column = new GridColumn(grid,SWT.NONE);
column.setText("1st");
column.setWidth(100);
GridColumn column2 = new GridColumn(grid,SWT.NONE);
column2.setText("2nd");
column2.setWidth(100);
column2.setTree(true);
GridColumn column3 = new GridColumn(grid,SWT.NONE);
column3.setText("3rd");
column3.setWidth(100);
GridItem item1 = new GridItem(grid,SWT.NONE);
item1.setText(0,"1st Item");
item1.setText(1,"1");
item1.setText(2,"2");
item1.setText(3,"3");
GridItem item11 = new GridItem(item1,SWT.NONE);
item11.setText(0,"2nd Item");
item11.setText(1,"4");
item11.setText(2,"5");
item11.setText(3,"6");
GridItem item2 = new GridItem(grid,SWT.NONE);
item2.setText(0,"3rd Item");
item2.setText(1,"7");
item2.setText(2,"8");
item2.setText(3,"9");
shell.setSize(500,250);
shell.open ();
while (!shell.isDisposed()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
}
When I run the application I can see the tree in the second column. when i
expand it the item in the second column (2nd row) is greyed out. can
someone tell me why i get this? is this a bug? i haven't managed to get
rid of it yet. further i wanted to insert a picture in one cell. but that
didn't work either (no picture was displayed). Is this a known bug or how
should that be done. when i run the application i noticed that when i
moved the cursor over the table it's kind of flickering. why is that? (i
haven't noticed that in the plugin-example). and one last question. is it
possible to have multiple lines in one row?
thanks in advance
regards

Hi Pete,
1.) 2nd row, 2nd column looks grayed (or selected). Turns out when I
built the latest drop, I forgot to remove a piece of test code (Doh!).
The cell at 2,2 is always selected.
2.) Picture in cell, that is not yet implemented. I am actually in the
process of adding that code now. You will be able to see pictures in
the next drop.
3.) Flickering, are you seeing the whole table flicker or just the
border? What platform are you on? If you are on Windows and you are
just seeing the border flicker:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=150274
4.) Multiple lines in cells/rows, it is possible but not supported by
the default rendering. If you wish to have multiple lines in each cell,
you will have to supply a new cell renderer.
I will be putting up a new drop later today or tomorrow that solves #1
and #2.

The code below looks like it should work (but it would not allow you to
dispose of the Image which is bad). How about a stack trace so I can
see what exactly is throwing the IAE.
Cell editors are supported through the GridEditor class. Its not
documented but it is essentially the same as TableEditor.

Hi Chris
thanks for your fast reply. I just downloaded the new release. The
selection of cell 2/2 is now ok, but I've still trouble with the image.
I'm keep getting an IllegalArgumentException. Can you maybe show me an
example of how you would insert the picture?
Regarding the flickering I can say that i'm running win xp pro. and it's
actually not just the borders it's the whole table that flickers. it looks
like as if the whole table is being redrawn or refreshed when moving the
cursor around. but as i said i don't have this problem with the example
plugin.
Ok, i'll have to see then. so multilines support is not planed in any near
future releases? about the releases in general: can you approximately say
when you'll be able to provide the first stable release?
thanks in advance.
regards

Setting an image:
GridItem myItem = new GridItem(myGrid,SWT.NONE);
myItem.setImage(1,myImage);
Who is throwing the IAE? setImage? Is the image not null and not disposed?
The table widget is redrawn when the cursor crosses cell boundaries to
support hover/mouse over effects. This is usually not noticeable
because of double-buffering. What version of SWT are you running with?
Can you attach your code?
Multiline support is not planned at the moment. I am still planning
significant new feature to Grid. I don't know when I will be complete.
Sorry.

Hi Chris
thanks for your answer. i tried to insert a picture as follows:
item1.setImage(6,new
Image(display,getClass().getResourceAsStream("/images/test.gif ")));
this way i always get an exception (IAE). when using a *.bmp images it
works. how would i insert any other format than *.bmp's?
the flickering is gone now since i upgraded to the newest version. thanks
for the hint.
by the way. do you have an example of how to use a cell editor or is this
not implement yet?
regards
