Extremely long lines: feature or bug?

[A.J. Bonnema]

Hi all,

I just found out a phenomenon on the wxPython sizers and I wonder =

whether this is a feature or a bug. The sample program attached to this =

message will show you what I mean:

1. If you run the sample as-is, you get one extremely long field (a lot =

longer than  the window or the screen)

2. a. If you change the parameter FLD_FACTOR from 1 to zero, all fields =

return to normal lengh.
    b. In stead of a, if you change the parameter of LBL_FACTOR from 50 =

to f.i. 2, the fields also return to normal length.

We have two BoxSizer here, both horizontal. The first contains a field =

and a label controlled by weights. The second contains an option group, =

controlled by a wx.EXPAND.

What happens here, is that the option sizer gets expanded to well beyond =

the window's borders, because the previous sizer is expanded because of =

the weights. I suspect, that a factor of 50 means, that -- whatever the =

window size -- the label will be extended to be 50 times the minimum =

length of the field on the same sizer. Unless the field has factor zero, =

in which case there is no reference for the label to expand.

What bugs me, is that wx.EXPAND and weights can get *way* beyond the =

window width. You could argue that a ratio of 50 to 1 is bullocks and =

the function works as designed, but you also argue that the sum of the =

lengths should never exceed the window itself.

So, I am left wondering: is this a feature or a bug?

Guus.
