Dynamic combobox content generated out of the model [message #720807]

Hi,

That is excellent: http://www.eclipse.org/forums/index.php/t/236688/
Is there anything similar available for custom combobox-widget?

E.g. The "Map-Sample" in sapphire.samples. You can enter new locations and routes. However there aren't any suggestions, when you created a route, which location you can choose. So for example, if you have two locations [Munich], [Shanghai]. A combobox inside the tableViewer opens filled with these options.

Is that possible?
cheers, Muki

Currently, our focus is on using the browse button approach to solve "possible values" scenarios, but there is an enhancement request open to provide an optional combo box rendering:

Also, work is currently in progress to hook-up CTRL+Space style of content proposals to text field property editor. This would work in conjunction with the browse button.

Hi Muki,

I tried this way,lets take the Ezbug example and we have IBugReport which has ProductStage property, by default Sapphire renders it with a radio buttons, if you want that to be changed to drop-down list you can just add an additional presentation hint "prefer.combo"

So your UI def (.sdef) for the drop-down property will look like ,

.....
<property-editor>
   <property>ProductStage</property>
    <hint>
         <name>prefer.combo</name>
          <value>true</value>
    </hint>
</property-editor>
.....

This will show the drop-down instead of the radio buttons.

PS: I use the latest stream build as I have the source code checked out and i build use from it. So please verify if this hint comes option for you in the "Hints" section of the property editor.

Just thought of suggesting it, please ignore it if this hit doesn't come as option with the version of Sapphire you are using.

The prefer.combo hint only works for Value<Enum> properties where the choice is between radio button or drop down list presentation. It does not work for Value<String> properties with PossibleValuesService. That's tracked here:
