Architecture design for Slicer flexible layouts

Back to Flexible Layouts Overview

Notes:

We discussed several ways of representing layouts including:

• html table style description

 <table name=A>
 <tr width=.5 height=.5>
   <td width=1.0 height=1.0>
     <table>
       <tr width=1.0 height=0.5>
         <td width=1.0 height=1.0> B </td>
       </tr>
       <tr width=1.0 height=0.5>
         <td width=1.0 height=1.0> F </td>
       </tr>
     </table>
   </td>
   <td width=1.0 height=1.0> C </td>
 </tr>
 <tr width=0.5 height=0.5>
   <td width=1.0 height=1.0> D </td>
   <td width=1.0 height=1.0> E </td>
 </tr>
 </table>

• Tk grid style description

 grid -row 0 -column 0 B
 grid -row 0 -column 1 -rowspan 2 C
 grid -row 1 -column 0 F
 grid -row 2 -column 0 D
 grid -row 2 -column 1 E

• tree description (sketched above)

 ???
 vtkSlicerLayoutFrame
    split[]
    GetNumberOfChildren()
    GetNthChild (int n)
    DeleteNthChild (int n)
    SetPaneContent ( *vtkObject)

 split[] = r.split(h,3,w=[])
 ???

And settled on the tree for its ease of programmatic manipulation. Ideas:

• Use swidget infrastructure for handling events using Bind to avoid triggering unwanted updates
