ui-tools implementation (ui-tools.cpp)

The following changes are in the code below, but are listed in case you already have the file and want to fix it yourself (and see the context of the problem).

Changelog Dec 15 2012 (second prob)
"Unknown error" msg issued when it's not an error.

Here's the fix. Whenever we call

Code:

  ok = find_slots(...);

we need to return 'true' without acting on the return values but not return 'false'...

Generic QT Signal/Slot --or-- Using Dummy Custom Widget in Designer -- No Plugin Req'd

[This is FUN!! It works. What a freaking trip. :-)]

The previous entry on using Old Style callbacks wasn't much of a hit. Ooooooohhhh... it's a hit alright.

But here it is in it's second incarnation cleaned up a bit though it needs a bit more simplification due to the number of elements that are involved and where they need to go. But this is cool.

QT4 dialog & using MC2 EXT_ALL target examples

Posted 12-11-2012 at 12:45 AM by rainbowsally

The sources are in the qt4 demos and you can use the pro file if you like, but here's example of how to use the EXT_ALL target in an mc2.def.

This also applies to makefiles in general, but it's much easier to work through an intermediate system such as mc2.

It is also a great demo for using dialogs, and you can choose native or QT built-in styles for them, which makes a big difference for the file and color selection dialogs.

I particularly like the file...
