CTabFolder - vertical tabs [message #718763]

Hi,

In our application we use a special implementation of CTabFolder to display the tabs on the right side of the folder.
As the implementation of CTabFolder in SWT and RAP differ very much it is not working because we used paintlisteners and GC (GC can only be used on Canvas, am i right?).
So i searched how the Control is implemented on the javascript side. There i found the "barTop" state and searched for it, but it is only used in AppearancesBase for drawing borders.
I looked over the custom widget example in the rap tooling help but i didnt find helpful information there either.
Thanks in advance

Hi Sam,
the client-side widget of CTabFolder (CVS HEAD) is
org.eclipse.rap.rwt\js\org\eclipse\swt\custom\CTabFolder.js. Or if you
are using 1.4 release it is
org.eclipse.rap.rwt.q07\js\org\eclipse\swt\custom\CTabFolder.js. I doubt
that you can easily implement the CTabFolder with the tabs on left or
right in RAP without creating your own custom widget.
Best,
Ivan

I found the CTabFolder.js already, there i found the barTop state.
My question was where the layouting takes place. The custom widget example has no layouting. I would be interested in where for example is the distinction between top and bottom tabbar in CTabFolder when it really comes to painting. As i said i found these states, but i didnt find where the really said: "Ok, state is top, so whe paint the CTabItems before the body". I didnt find documentation on layouting complex widgets like Tabfolders.
Thank you for your help.

Hi Sam,
there is a field in the CTabFolder onBottom witch is rendered on the
client trough the CTabFolderLCA#writeTabPosition. Than the actual layout
take place in CTabFolder.js#_updateLayout. The actual CTabItem client
side widget is CTabItem.js and the corresponding LCA is CTabItemLCA.
HTH,
Ivan
