[Fxruby-users] Multi-colored FXList

[Matthew M. <nam...@na...>]

Hello,

On the fifthplanet wiki I saw one answer to a question I hadn't asked yet ;^)
The question dealt with subclassing FXList to draw the list items in different
colors. Lyle provide a very good solution in C++. I'm wondering if, using his
solution as a guide, the same result could be done using FXRuby. I thought I
would ask and see if there were any gotchas before I tried an implementation in
Ruby.

I've one more question as well. The way that I'm learning FXRuby is to write a
file manager that is similar to the one called sfm that was written using
GTK+. When renaming a file in sfm the equivalent of a FXLabel is replaced by a
one-line text field where the filename can be edited (i.e. the same way that the
Windows Explorer works.)

FXList doesn't support this behavior. Now I'm wondering how to write a widget to
do what I want. I've looked at the C++ source for FXList and hope that here is
an easy way to accomplish the behavior I see in sfm. After doing some reading I
thought that I might could use a FXVerticalFrame to stack the widgets that show
the filenames. The trouble is that I couldn't find a way to iterate through the
contents of the frame and if necessary replace a FXLabel with a FXTextField
object. Well, there is the FXWindow#children method in the FXVerticalFrame
subclass, but would replacing an element in the returned array with a different
widget affect the display?

Well, for both these things I'm looking for some insight. Thanks.

Matthew.
