Hi,

I want to display a check box, read only text and a button in a single =
cell of CTableTreeItem.
I created a custom cell having the following createTitleContents() ...

protected void createTitleContents(Composite contents, int style) {
contents.setLayout(new FillLayout());

checkBox =3D new Composite(contents, SWT.WRAP);

checkBox.setBackgroundImage(checkBoxImage);

text =3D new Text(contents, SWT.BORDER | SWT.WRAP);

browseDomain =3D new Composite(contents, SWT.WRAP);

browseDomain.setBackgroundImage(browseDomainImage);

}

But nothing is displayed and the UI is scrwed up!

How should I create my custom cell ?

I also need to display a dialog box as the user clicks the button. Is =
it possible to handle button selection within this cell ?

TIA

Kaniska

Hi

>But nothing is displayed and the UI is scrwed up!

There's a property of FillLayout that tells the composite to fill
horizontally or vertically, it may be trying to fill horizontally...or try
maybe a GridLayout with numColumns=1 and each control has
gridData.grabExcessHorizontal=true

>I also need to display a dialog box as the user clicks the button. Is it
>possible to handle button selection within this cell ?
add a selectionListener to the button, in the widgetSelected() method put
the code to open the dialog

Hi

Just thought that you might *want* the controls to display horizontally
aligned..
I'm a newcomer myself so grain of salt..I'm not sure how to get the effect
you want with FillLayout, but with another layout like FormLayout you can
specify distance between controls and have controls grab excess space...

In code below the "top" of the comboProjectName control is 2pxls away from
the labelProjectName control, 10pxls away from the "left" of the composite
and 10pxls away from the "right" of the composite.

composite.setLayout(new FormLayout());
....
//PROJECT LIST COMBO
comboProjectName = new Combo(composite,SWT.DROP_DOWN);

formData = new FormData();
formData.top = new FormAttachment(labelProjectName, 2);
formData.left = new FormAttachment(0, 10);
formData.right = new FormAttachment(100, -10);
comboProjectName.setLayoutData(formData);
.....
.....

Hi Kaniska,

Just to make sure, is the SWT.TITLE style bit being set in the
constructor of the cell?

something like this:
public MyCell(CContainerItem item, int style) {
super(item, style | SWT.TITLE);
}

also, could you also expand a little on "the UI is screwed up" :)

cheers
