[Solved] Openbox Ignoring Titlebars, Odd Resizing Problems

Question

Alright, so I'm trying to set up my Openbox to have some manual window tiling support similar to Subtle's implementation.
My screen is 1600x900.  I have 1 pixel margins all around except for a 41 pixel margin on the East side of the screen.
Here are some of the appropriate parts to my rc.xml:
<keybind key="W-KP_3">
<action name="MoveResizeTo">
<x>-0</x>
<y>-0</y>
<width>458</width>
<height>449</height>
</action>
</keybind>
<keybind key="W-KP_9">
<action name="MoveResizeTo">
<x>-0</x>
<y>+0</y>
<width>458</width>
<height>449</height>
</action>
</keybind>
So, if my screen is 900 pixels tall, with 1 pixel margins on top and bottom, that should mean that I have 898 pixels to work with vertically.  898/2=449, so by setting the window the be resized to a height of 449 pixels should mean that the window will take up exactly half of my screen vertically.  Unfortunately, it seems that Openbox does not include the titlebar in all of this so when I have two terminal windows.  This means that when I have a window set to W-KP_3 and another at W-KP_9 (bottom right and top right), the windows will overlap. 
Is there any way to fix this without undecorating my windows?

Answer 1

It's just a wee bit of math and a couple of test runs to correct this.  Your title bars plus windows borders appear to be 14 to 20 pixels in height.  So change your desired height from 449 to 433 (16 pixels difference), test it, and adjust the value up or down from there.
If you are using xterm, the window will not necessarily be the full height you specify.  On my display, where I normally don't use window decorations, xterm won't allow a window to include a fraction of a line height.  You might want to run your height tests with a different app.
Here's an old shot of my tiling.  I deliberately leave a gap between tiles.
