ArrayCtrl: how to set column width? [SOLVED] [message #192]

I want to individually set the column widths for the
ArrayCtrl. How do I go about doing this?

I want it so that the Columns automatically size depending
on the length of the field under the column. I already
compute this largest "size" by getting the largest for
all row occurrences of the field.

The Problem now is to set the column width, The default
behaviour of the ArrayCtrl is that it sets all column width
to the same size and tries to fit all the columns in the
ArrayCtrl "client" area so that it doesnt even show the
horizontal scroll bar.

Sorry for my questions but since these controls dont have
much in a way of documentation I end up guessing. Looking
at the header files and method names doesnt help either
especially if the method names are short and obscure.

You can do this when you add columns:

arr.AddColumn("Col 0", 100)
.AddColumn("Col 1", 50);

or after creating array

arr.HeaderTab(0).SetRatio(500);
arr.HeaderTab(1).SetRatio(1500);

Actually, ArraCtrl is the best documented widget in the library Smile

http://upp.sourceforge.net/src$CtrlLib$ArrayCtrl$en-us.html
http://upp.sourceforge.net/src$CtrlLib$HeaderCtrl$en-us.html

To have horizontal scrollbar, you need to change the mode of HeaderCtrl of ArrayCtrl to absolute

arr.HeaderObject().Absolute();

and then numbers passed as column witdth will be in pixels.
