Problem with Custom Widgets at higher display scaling [message #1853073]

Hello,

We have implemented several custom widgets for the properties. We ran into a problem where if (on Windows at least) the user sets their display settings to be 125% or 150% scaling, the custom widgets are not given enough room in the properties panel and they overlap each other. (it works fine at 175% scaling)

The attached image 100pScaling is how it looks at 100% scaling, and it is fine.

index.php/fa/42196/0/

The attached image 125pScaling is how it looks at 125% scaling, and you can see that the widgets overlap each other and are not fully displayed.

index.php/fa/42197/0/

Is there a way we can implement something on our end to correct this, or should I submit a bug report?

Thanks,

Louis

Hi,
We can't seem to reproduce this using the standard widgets.
It's difficult to know if the issue in your custom code without knowing it. The only thing I can think of is: are you using the EEFWidgetFactory to create your widgets?
It inherits from org.eclipse.ui.forms.widgets.FormToolkit which normally ensures all widgets are correctly styled and configured.

Thank you for your response.

For most of the widgets, we are using the EEFWidgetFactory gotten from an IEEFFormContainer using the method getWidgetFactory.

However, the tables that are to the left of the buttons are NatTables, which can not be created from the EEFWidgetFactory.

Thanks,

Louis

For closure, the problem was simply that I was using a height hint for the composite that contained the table and the buttons. Changing this to a minimum height solved the issue.
