[Ktechlab-devel] Pushed fixes to github

Fri Nov 27 22:14:36 UTC 2015

Hi,

I have pushed a new set of fixes to github:

https://github.com/ktechlab/ktechlab-0.3/tree/port-0.3.8-kde4-v1

- The circuit redrawing / scrolling issues should be mostly fixed. Zooming
in and out should mostly work. This means that now circuits bigger than the
window should be usable. No warnings should appear in the terminal from Qt,
about widget drawing.

Feel free to test, any feedback is welcome.

I'm sending below the list of remaining things to be fixed.

- created subcircuits appear twice in the subcircuit list, and in some
cases they cause crashes; investigation needed

- (from Claus) There are some other gfx glitches, but that might be because
I run it in a virtual machine - didn't have them on the previous builds
though.
    - needs checking

- Gfx error on e.g. LED in that I can't connect a wire unless I rotate the
part.
- some components get their connectors moved, thus (1) graphical issues,
(2) impossibility of connecting connectors results

- Som gfx errors that leaves gaps at connection points on components.
  (see last email with attached screen shot)

-'Scope works well, but doesn't clear 'lines' from other circuits when they
are closed. (Y-axis scale would be nice)

-I think the 'scope just keeps filling data points into RAM, because RAM
usage climbs steadily until the virtual machine crashes (same as the kde3
version)

- components have no description
   - the context help exists; or something else is needed here?

And the issues from the TODO file:

Features needs re-implementation at Qt4 port
=======
- dbus integration for documents (used to be dcop bindings for documents)
- undo / redo interface needs to  be fixed for text documents: this
interface is not exported by KDE4 KTextEditor

- printing a text document needs fixing
