* bugs
|
|
|
|
|
|
|
|
- There is a pretty strange bug in kig when you use the accel keys.
|
|
|
|
Open Kig, type p to start constructing a point. Click somewhere to
|
|
|
|
construct one. Now click p again, and press escape to cancel the
|
|
|
|
construction. It will not work, and you will have to construct as
|
|
|
|
many points as times you pressed escape ( or perhaps the times you
|
|
|
|
pressed esc square or sth like that ). Anyway, this is due to how
|
|
|
|
Kig works with some strange Qt event loop stuff to make its modes
|
|
|
|
work, along with a strange way in tdeaccel of working. I have a
|
|
|
|
patch against tdecore/tdeaccel.cpp that should fix it, but the real
|
|
|
|
fix is to get rid of the entire event loop stuff and think of a
|
|
|
|
better way to manage all this. pino: seems pressing the stop button
|
|
|
|
n times, where n are the times you pressed escape, cancel all the
|
|
|
|
constructions, so the problem is the behaviour of escape.
|
|
|
|
|
|
|
|
- The polar coordinate system blocks Kig when zooming. Select the
|
|
|
|
polar coordinate system, use the Select shown area tool ( or your
|
|
|
|
favorite zooming tool ) and select a specific part of the document.
|
|
|
|
Smaller parts of the document cause bigger problems. pino: this is
|
|
|
|
due to the polar grid: try to make zoom if there is no grid.
|
|
|
|
|
|
|
|
* I/O: filters, exporters, ...
|
|
|
|
|
|
|
|
- add other command line options, like:<br />
|
|
|
|
-e, --export-to FORMAT file.kig => Kig will export file.kig ( or any
|
|
|
|
other supported format ) into file.ext ( even more than one file ).
|
|
|
|
The output format depends on the FORMAT string. domi: this is more
|
|
|
|
difficult, because the export plugins require extra parameters.
|
|
|
|
E.g. the ImageExporter needs an image size etc.
|
|
|
|
|
|
|
|
- filters: more input filters; improve the existent ones ( see
|
|
|
|
filters/*-filter-status.txt ); add the possibility to ignore errors
|
|
|
|
on loading
|
|
|
|
|
|
|
|
- "export to *": add stuff like java applets, kmplot documents, etc...
|
|
|
|
|
|
|
|
* objects
|
|
|
|
|
|
|
|
- Two new transformations: projection on a line, orthogonally and
|
|
|
|
according to a given direction. As a mathematician, I'm supposed to
|
|
|
|
have a grudge against these, as they don't fit the definition for
|
|
|
|
affine transformations ( the matrix has to be regular ) ;), but I
|
|
|
|
suppose high-school students may find them useful. However,they
|
|
|
|
would give rather useless results for e.g. lines ( all curves are
|
|
|
|
almost always projected on a line, segment or ray that you wouldn't
|
|
|
|
see because it's equal to the line we project upon ). It would be
|
|
|
|
useful for points though.
|
|
|
|
|
|
|
|
- make DoubleImp a "visible" object with uses like Dr. Geo numeric
|
|
|
|
values.
|
|
|
|
|
|
|
|
- Provide some nice stuff for differential geometry: velocity vector
|
|
|
|
of a curve, curvature vector, osculating parabole. Most of this is
|
|
|
|
not too difficult to implement, but very cool :)
|
|
|
|
|
|
|
|
- create a formula label to display math formulas in the document, and
|
|
|
|
allow for importing from/exporting to other formula formats such as
|
|
|
|
KFormula, OOFormula and MathML.
|
|
|
|
|
|
|
|
- other types of fillable shapes, like arc sector, arc segment...
|
|
|
|
|
|
|
|
- defined integrals, as a particular case of filled shapes.
|
|
|
|
|
|
|
|
- improve *a lot* the transformation support for cubics.
|
|
|
|
|
|
|
|
* GUI
|
|
|
|
|
|
|
|
- make stuff from RMB menu's accessible from other places as well.
|
|
|
|
|
|
|
|
- Add the possibility to select, via new dialog, one or more types of
|
|
|
|
object.
|
|
|
|
|
|
|
|
- add a magnifying glass/zoom window to magnify "on-the-fly" a part of
|
|
|
|
the document.
|
|
|
|
|
|
|
|
- improve the KTextEditor interface in the script code wizard.
|
|
|
|
|
|
|
|
- make the dialogs not pop up over the main window.
|
|
|
|
|
|
|
|
- add QTooltip and QWhatsThis to the widgets in the various dialogs
|
|
|
|
(export dialogs, types dialog, ...)
|
|
|
|
|
|
|
|
* core
|
|
|
|
|
|
|
|
- When selecting an argument of a certain type, maybe we should check
|
|
|
|
whether the required arguments are really there, before telling the
|
|
|
|
user to select them. Then we could give an error telling the user
|
|
|
|
to first construct the other objects. An exception should be made
|
|
|
|
for points of course.
|
|
|
|
|
|
|
|
- Add the possibility to attach text label also to angles.
|
|
|
|
|
|
|
|
- add the possibility to transform more than one object at one time,
|
|
|
|
using the popup menu. For example, I select two circles, I choose
|
|
|
|
Transform->Translate form the RMB menu and then Kig should ask me for
|
|
|
|
a vector to use to translate all the selected objects.
|
|
|
|
|
|
|
|
- add support for work with other measure units (cm, inches, etc...)
|
|
|
|
than just pixels...
|
|
|
|
|
|
|
|
- extend ObjectFactory::sensiblePointCalcer to also construct
|
|
|
|
intersection points of stuff... (pino: done for lines)
|
|
|
|
|
|
|
|
- when moving an object that wants to move its parents, try to check if
|
|
|
|
it is itself not an indirect child of one of the parents it is
|
|
|
|
trying to move, and forbid the move in that case, as it will lead
|
|
|
|
to chaotic behaviour. I am not sure if this is really well
|
|
|
|
possible, but I have to look at it.
|
|
|
|
|
|
|
|
- add intersection types: arc-arc; arc-conic; arc-cubic; conic-cubic;
|
|
|
|
cubic-cubic; locus-other object.
|
|
|
|
|
|
|
|
- rework the ObjectConstructor and GUIAction stuff into something more
|
|
|
|
general, and more clean. See the comment for
|
|
|
|
ObjectConstructor::constructMode().
|
|
|
|
|
|
|
|
- figure out a way to allow the user to enable and disable certain
|
|
|
|
features. E.g. I have been asked to allow the user to limit himself
|
|
|
|
to compass-ruler constructions..
|
|
|
|
|
|
|
|
- add another viewmode ( which would be completely orthogonal to the
|
|
|
|
KigMode concept ), where you can more clearly see the dependencies
|
|
|
|
in a figure. Something with colours, numberings, and/or a tree-like
|
|
|
|
text representation of the dependencies..
|
|
|
|
|
|
|
|
* scripting
|
|
|
|
|
|
|
|
- Python scripting: export cubics for real, improve existing API.
|
|
|
|
|
|
|
|
- make the scripting system work more like the macro system. Make it
|
|
|
|
a way to define new object types that can be reused more than once,
|
|
|
|
instead of making it just a way to add *one* object.
|
|
|
|
|
|
|
|
- support for more scripting languages than just Python.
|
|
|
|
|
|
|
|
* other
|
|
|
|
|
|
|
|
- document mathematical i18n strings, so that the translators have a
|
|
|
|
clue about how to translate them !
|
|
|
|
|
|
|
|
- write cabri-filter-status.txt.
|
|
|
|
|
|
|
|
- add "Tools": easy tools designed for geometry, like Angle converter and
|
|
|
|
so on...
|
|
|
|
|
|
|
|
- save a "session", i.e.: record how a document is moved, and save it to
|
|
|
|
e.g. a flash file or something like that.
|
|
|
|
|
|
|
|
- koffice support ?
|
|
|
|
|
|
|
|
* future ?
|
|
|
|
|
|
|
|
- there should be a way to link a figure to a (html?) file containing
|
|
|
|
exercises. Teachers would be able to create exercises for Kig.
|
|
|
|
I'm thinking of doing this with HTML (& TDEHTML) + scripting ( but
|
|
|
|
this is _distant_ future.. )
