Is dynamic resize of Combo possible? [message #461282]

Hi all,
My scenario is : I have 2 combos in a Composite. Depending on the value
selected in the first Combo, the second Combo is populated. Now the values
in the second combo are of variable length, so i need to resize the combo
depending on the length of the text. Is it possible, since we place the
combos on the composite in the beginning itself ?

Code:

msgFmtCmb = new Combo(paramComp, SWT.READ_ONLY);
gridData = new GridData();
gridData.horizontalSpan = 2;
msgFmtCmb.setLayoutData(gridData);
msgFmtCmb.addModifyListener(this);

msgTypeCmb = new Combo(paramComp, SWT.READ_ONLY);
final GridData grdDataMsgType = new GridData();
grdDataMsgType.horizontalSpan = 2;
msgTypeCmb.setLayoutData(grdDataMsgType);
msgTypeCmb.addModifyListener(this);

In the modifyText method, i am removing all values from the second combo
and adding new values.

try to call to the "pack()" method of the combo that you want to resize dynamically into the listener.

did you try to layout the parent composite when the values of your 2nd
combo are modified ?
