Fox questions

I’ll return to Tycho when I’m less busy, but right now I’m stuck on
some Fox issues. I could continue to develop it without grokking
these things, but I don’t really want to.

  1. Given an FXTreeList wherein I add or change an item, how do I get the
    tree to redisplay?

  2. Given an MDIClient where I add or resize an MDIChild, how do I get it
    to display?

  3. Given an MDIChild with a textbox inside it, can I click on the window
    frame and select the window without giving focus to the textbox?

#1 and #2 are obviously variations on a theme. I’ve tried various
permutations of create, show, repaint, recalc, refresh and one or two
others.

Is there a method called just_show_me_the_damned_widget ?

IIRC (I don’t have the app running in front of me now) it just worked
when I added a new item:

leaf = tree_list.addItemLast(…)
tree_list.expandTree( tree_list.currentItem )

  1. Given an MDIClient where I add or resize an MDIChild, how do I get it
    to display?

This worked for me:

mdi_child = FXMDIChild.new( mdi_client, …)
mdi_child.create()

    frame and select the window without giving focus to the textbox?

Sorry, I don’t know; maybe it’s possible to intercept whatever message
goes down through the MDIChild to its child.

It may have been renaming items that was the issue. I’ll check.

It doesn’t for me.

Out of curiosity, what is your version of fxruby and of Fox?

Thanks,

For this app, I’m using the PragProg 1.6.8 windows build of Ruby; When I
ask it for Fox::VERSION, it tells me ‘1.6.7’.

I’ve found the odd niggle with FXTree, but I haven’t had any problems
with MDIClient/Child. There’s a simple sample with the FXRuby
distribution called mditest.rbw; maybe that’ll work for you?
