Back to Flexible Layouts Overview

Adding multiple tabs to a Slicer application window

• Challenge: Will be useful to specify and switch among multiple tabs in the main application window.
  • Each tab can display a layout, and that layout may include multiple views, multiple module guis, etc.
• Displaying multiple module guis at once requires each module UI to contain module select/navigate controls.
• Need controls for adding a tab, deleting current tab.
• Slicer starts up: first time user sees welcome module in a single tab.
• Slicer starts up: returning user sees their tabs from last session restored.

Open questions

• What is the desired behavior when user selects a module from the toolbar?
  • switch the currently raised tab's GUI.
• What happens when user selects "+" to add a new tab?
  • new tab is added with same layout as previously raised tab.
  • what module is selected -- home? none?
• What happens if the layout contains multiple GUI panels and user selects a new module from the toolbar?
  • new module GUI replaces last module GUI to be touched

Default layout at startup

Ok: we've just fired up Slicer and we see the following presentation (which is presumably restored from the application registry).

• We see Slicer's Logo
• The data module (my home module) is presented
• A first tab indicating this module is shown (and indicator that shows I can create other tabs).
• The data module GUI now contains controls for changing the raised module, or navigating among previously used modules.
• If I use the module selector, or the module shortcuts in the toolbar, the tab name will change to reflect the module selected in this tab.
