Description

This commit changes the gui for the code generators task selection. It shows all titles and descriptions of the task next to their buttons and not only the button, but also the text is clickable.
It also removes the arbitrarily default selected task, so the user has to actively choose a task before he could continue.

• Can you change the icons with their respective explanation into one clickable button?

• Can you also add shadows to the buttons?

• Can you change the icons with their respective explanation into one clickable button?

Buttons cannot hold a layout. Hence it is not possible to put all text well formatted into it.
A workaround is, to put the current button into the group with the text.

• Can you also add shadows to the buttons?

So with the workaround, the button is actually a SWT Group. You can add shadow as a style to each group, but on my display it didn't show any effect.

Futhermore I tried to work with different colors for the selected items, but that will lead to issues with different color themes, e.g. the dark mode. An alternative is, to make the button a radio button. A screenshot of how it would look like is here:

@marvinvo Is the screen sizable? If so, do we have scrollbars or a dynamic button layout so everything can be visible. E.g in the last screenshot it looks like the last item group got cut off.

The window is resizeable. Also all items are contained in a ScrollableComposite, which can scroll vertically and horizontally through the list.
I could try to make the scrollbar permanently visible when content is overflowing.
