[Gtk2hs-users] How to make split half Paned?

[Andy S. <laz...@gm...>]

Hi all,

Now i'm developing a multi-paned application.

Example i have root paned named paned1 (VPaned)
If i want split paned1 with two paned. 
I can use below code:

 Step (1)

    panedPack1 paned1 paned2 True True
    panedPack2 paned1 paned3 True True

And then two children paned is split paned1 vertically, and them height
is *half* of paned1.

It's okay now.


Next i need split paned2 horizontally with two paned.

So i need remove paned2 from paned1.

 Step (2)

    containerRemove paned1 paned2

Then i add panedTemp (HPaned) to paned1

 Step (3)

    containerAdd paned1 panedTemp.

And i add new children paned to panedTemp

 Step (4)

    panedPack1 panedTemp paned4 True True
    panedPack2 panedTemp paned5 True True
    
Now paned1 is split to *three* children paned.

But problem occur, the height paned4 and paned5 of not *half* of paned1.

But if i remove paned3 from paned1 in Step 2:
    containerRemove paned1 paned3

And children paned's height is *half* of parent paned.

And result is if remove *first* child paned from parent paned, *second*
paned will grow it's size.

But i want keep them always half of parent paned.

So have any way keep other child paneds' size don't change if i remove
one child paned from parent paned?

Thanks!
