(OT) wxPython & resizers, html text (code included)

[flupke]

Hi,

i'm trying to convert my java console app to a python gui.
Now, the only problem i seem to have at the moment are the resizers
for the layout. It seems that for the purpose of what i'm trying to do,
specifying the coordinates is easier that fighting with the layout resizers.

1) I have a screen split in 2. Left side is a textcontrol where logging will
end up. All text will be appended to the textcontrol. Ideally this should
allow html tags but the wxHtmlWindow doesn't seem to support just adding
text. Only workaround that i can think off is to maintain a list of message
myself
and then i could set those every time something changes but i don't really
like this as on every change, the whole textcontrol will be refilled.
The reason for html is to easily adjust text from one colour to another and
for
instance some basic formatting like bold, italic etc.
Any ideas?

2) (view with for instance with courier)
-----------------------------------------------
| TextControl | ________ |
| ||________| Combobox |
| | |
| | ________ |
| ||________| |
| | |
| | ________ |
| ||________| Textcontrol |
| | |
-----------------------------------------------

Basically i have a number of button left-aligned in the right part of the
split window and
they are placed vertically with a small gap in between (border). This is
working but then
i would want to add a combobox next to button 1 and saya textcontrol to
button 2.
A gridresizer would work if i would be able to specify what row and column
the component
would have to be in but there doesn't seem to be such a method.
Only sollution i can think of is adding the coordinates of where i want to
component to come.
Is there another sollution as i read that it's best not to add components by
specifying an x
and y value.

Thanks

Check out Dabo (www.dabodev.com); they are creating an IDE for wxPython that
uses direct placement. It's still young, but does work.
