Updating contents.rect.height

じ☆ve冰风

Hello everyone,

This question is in regards to updating the contents rect so that the scrolling arrow is not displayed.
I have a window that is created and it displays information (of course).
When the window is first created it does not have any data to display. when items are selected the data is then displayed.
What I'm trying to do is to adjust the window height based on how much data is displayed.
The issue is that if I specify the item_max to 0 (when no data is displayed), then nothing is shown.
The contents.rect is actually [0,0,1,1]
If I set the item_max to the largest number (4) then the data is displayed. The contents.rect is [0,0,104,96]
So some items will have 1-3 lines displayed and not 4, so I've been able to adjust the window height for this, but this causes the scroll arrow to show as the contents height is larger than the window height.
I have tried to change the contents height, but it just doesn't seem to want to change no matter what I do.
contents.rect.height = 48. This results is no change.

How can I update the contents height based how how many lines to display?

* figured it out

After taking @kyonides suggestion, I did some testing and eventually found the Window_Base method create_contents.
This showed me how the contents bitmap is created for the window. Then it was easy.
