Re: [ptp-dev] Minimum expected display size for Eclipse user?

[wspear <wspear@xxxxxxxxxxxxxx>]

Greetings,

I'm not sure if this is applicable to your situation, but when I was creating scrollable tabs for the TAU plugins, this was how I did it.  I found it looked better having each tab scroll individually, rather than putting the entire tab-group in a scrollable composite.  That avoids having a lot of blank space on the bottom of tabs shorter than the longest tab.  The tricky bit, I found, was making sure to specify a 'sane' minimum size.  This only applies to vertical scrolling, but it should be easy to apply it to horizontal.

Regards,
-Wyatt


       //Define the top level composite and tab parent
       Composite comp = new Composite(parent, SWT.NONE);//parent provided as an argument
        setControl(comp);
        FillLayout topLayout = new FillLayout();
        comp.setLayout(topLayout);
        TabFolder tabParent = new TabFolder(comp, SWT.BORDER);

//Repeat approximately the following for every tab:

        TabItem anaTab = new TabItem(tabParent, SWT.NULL
);
        anaTab.setText("Tab Label");

        ScrolledComposite scrollAna = new ScrolledComposite(tabParent,SWT.V_SCROLL);
        
        Composite anaComp = new Composite(scrollAna, SWT.NONE
);
        anaTab.setControl(scrollAna);

        anaComp.setLayout(createGridLayout(1, false, 0, 0));
        anaComp.setLayoutData(spanGridData(GridData.FILL_HORIZONTAL, 5));

//Insert all of your actual tab content here, using anaComp as the parent
//Conclude the tab area with this (adjusting names as necessary for individual tabs):

        anaComp.pack();
//This gets the approximate height of the composite as rendered; a good minSize for the scroller
        int anaCompHeight=anaComp.computeSize(SWT.DEFAULT, SWT.DEFAULT).y;
        
        scrollAna.setContent(anaComp);
        scrollAna.setMinSize(400, anaCompHeight);
        scrollAna.setExpandHorizontal
(true);
        scrollAna.setExpandVertical(true);

There's a decent example here

But that's from the eclipse help which Doug said didn't help....
it's just that this is a better example than most eclipse help anyways.
It explains two different way to use it.
I have *not* tried this, so take it for whatever it's worth, possibly
nothing.

ScrolledComposite is evil. The last time I tried, I just kept hacking away
at the options until it worked. And even then it didn't work exactly how I
wanted. There must be examples out there. The Eclipse help didn't help at
all.
