How to remove toolbar( bootom and top) both from Screen Layout of TAB Workplace??
Go to workplace structure & for that particular workplace for which you wants to remove the toolbars. Now in aspect windows, select Application Bar & Status Bar aspects. when you click application bar aspect, under Main window tab uncheck "Show fixed displays". for status bar also do the same & check. It will work.
You may have to rebuild the frame configuration depending on how you want to present the toolbar, or if you don´t want toolbar at all. Their is a couple of predefined frame configurations that you can find in Library Structure -> Workplace Frames.
Then in ScreenLayout XML configuration you have to point on the frame you would like to use.
In the application bar you can do as previous answer describe.
Great luck to you.
