How to adjust the width of master details screen ratio in Eclipse RCP?

Question

I am using MasterDetailsBlock on my FormPage. I would like to adjust the screen width for the master and details part of the form. I had been searching around and haven't found a way to do it. The documentation seems to suggest it is doable through the SashForm, but I do not see how.

It will be great if I can use percentage ratio, like the FormAttachment style, but if that is not possible..I'm ok to fix the master and details to specific pixel also.

Answer 1

Just use SashForm.setWeights(int[]) to modify the weights of the master and the detail in the MasterDetailsBlock.

The weights describe the size ratio of the SashForm's parts. {1, 2} for examble would make the detail twice as wide as the master.

Answer 2

In your MasterDetailBlock class, override the registerPage() method, set your all detail pages, then call sashform.setweights(int [])

Example:

protected void registerPages(DetailsPart part) {

    part.registerPage(MemoryBudgetImpl.class, new MemoryBudgetDetailPage());
    sashForm.setWeights(new int[]{1,3});

}
