Filter ComboBox content prior to its expansion [message #1404548]

Hi,
I am trying to implement a JFace ComboBox that very first time (when user did not select anything yet) displays a text inside it: "<Select>". When the user clicks on combo box to expand it, I want to display a list of files from some pre-defined directory (I know how to do that) but not the string "<Select>" (I don't know how to do that how to remove the first element <Select> prior to combo box expansion).
Any help appreciated.
Regards,
Janusz

Hi,

If your combox isn't read-only (without SWT.READ_ONLY style), then you can use Combo#setText(String) method to set the default text.

If your combobox is read-only, then

1. Add the "<Select>" by default in your input of the comboviewer
2. Add a FocusListener to the combo and override the method focusGained to reset the input without the "<Select>".

regards,

Hussein
