Port to the new KPluginFactory API.

Commit by saxton :: r653797 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/ (6 files):

Polishing of the undo/redo: make sure the current state is saved when something happens.

Commit by saxton :: r653656 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/ (6 files):

Speed up differential equation calculating by several hundred percent. The main lesson learnt today is to be wary of Qt's implicit sharing: Although it speeds up some usages, repeatedly freeing memory (on operator=) and then allocating memory (on detach()) can be overall a lot slower.

Commit by saxton :: r653540 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/equationeditor.ui:

Make sure the buttons stay nice sizes when the equation editor is made large.

Commit by saxton :: r653539 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/ (kmplot_part.rc kmplot_part_readonly.rc):

Move the coordinates dialog from the edit menu to the view menu; I think it's more appropriate here.

Commit by saxton :: r653538 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/ (6 files):

Don't bother trying to be clever about the order that functions/constats are loaded in (see bug 143747); instead just reparse everything once everything is loaded. This solves complex dependencies such as constants being defined in terms of functions, etc etc.

Commit by saxton :: r652241 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/ (6 files):

Small tweaks to the UI.

Commit by saxton :: r652239 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/function.cpp:

Fix extraction of variables in functions when they contain spaces (e.g. "f( x )" instead of "f(x)"), also add a "k" variable for parameters when the expression is of the form "y = ..." (instead of "f(x) = ..." or "f(x,k) = ...") so that parameters can still be used.

Commit by saxton :: r652237 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/ (parser.cpp parser.h):

Fix some crashes when an empty string is entered for a function, and some optimizations for parsing expressions.

Commit by saxton :: r652005 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/ (14 files):

Added a quick and simple calculator. This replaces the "plot value" tool.

Commit by saxton :: r651930 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/ (8 files):

Improved sliders dialog: the min/max values for each slider can be edited in place (instead of right-clicking), and allow full expressions for the values.

Commit by saxton :: r651885 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/ (constants.h parser.cpp):

Some fixes for parsing expressions where names of constants may be the start of a function name, or vice versa.
For example, if there was a constant "s", then "sin(x)" would be parsed as "s*in(x)".

Commit by saxton :: r651735 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/kprinterdlg.cpp:

Fix printing; some internal change in kprinter caused the extra option values to default to zero, which unfortunately included the width and height of the output image.

Commit by saxton :: r651734 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/ (functioneditor.cpp kconstanteditor.cpp):

Give icons to some more buttons.

Commit by saxton :: r651733 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/ (5 files):

Improvements to the parameter list editor:

• Given icons to buttons.
• Added "move up" and "move down" actions to change ordering of parameters.
• Allow scrolling through the parameters with up/down keys.

Commit by saxton :: r651725 kmplot/trunk/KDE/kdeedu/kmplot/ (9 files in 2 dirs):

Lots of small cosmetic improvements.

Commit by saxton :: r651613 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/maindlg.cpp:

Use the new QSvgGenerator from Qt 4.3 for exporting to SVG. This means that kmplot is now qt3 free!

Commit by saxton :: r651588 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/ (kmplotio.cpp kmplotio.h parser.cpp):

Fix a couple of bugs when saving functions that depend on each other:

• Give functions an id *before* the rest of them is loaded, not after. This fixes dependency checking.
• Save the functions in such an order that functions required by others will be loaded first. BUG: 143747

Commit by saxton :: r651576 kmplot/trunk/KDE/kdeedu/kmplot/kmplot/view.cpp:

Improvements to drawing of axis labels (make sure they aren't truncated at the edge of the view, make sure they don't overlap the axes for large font sizes).

Commit by saxton :: r651573 kmplot/trunk/KDE/kdeedu/ (25 files in 2 dirs):

Replace "Coordinate System {I,II,III}" actions with "Reset View". The three actions were excessive since the coordinates can be changed quickly anyway; one action to reset the view is enough.

BUG: 139106
