wxMotif TODO
------------
Updated: 28/12/98
-------------------------------o-------------------------
General comment: see the following site for useful Motif widgets.
ftp://ftp.x.org/contrib/widgets/motif
Also, grep for TODO comments in source.
High Priority
-------------
- Have a central/per app file for colour settings, with a wxWin
app to allow changing settings interactively.
- Colour setting in widgets (almost done). Should scrollbars take
on the background colour? Not right for e.g. wxScrolledWindows,
so maybe have wxSystemSettings value for scrollbar colour, and/or
ability to set scrollbar colour independently.
- Optimize wxWindow OnPaint to avoid flicker, collapsing Expose events
as per flicker fix in 1.68. It will be tricky to avoid
interfering with non-wxScrolledWindow widgets except by
explicitly testing for wxScrolledWindow.
- Implementation of OnEraseBackground. How? Call OnEraseBackground
just before OnPaint? Will duplicate Xlib's own erase of the background.
However, this is usually OK, because the default wxWindow::OnEraseBackground
can do nothing (SetBackgroundColour will make the background look OK).
And if a custom OnEraseBackground uses the same colour as the window
background, no flicker will be seen. If it does something else, such as
painting a tiled bitmap, then a slight flicker might be seen unless
X can be persuaded not to repaint the window background by default.
- wxNotebook bug: why doesn't the notebook sample appear until the
user resizes the window again? But it's OK for MDI. Strange.
- wxSpinButton
- Miscellaneous events.
- Get wxGLCanvas from 1.68 working.
Low Priority
------------
- Visuals: how to select an appropriate one?
- Work out why XFreeFont in font.cpp produces a segv. This is
currently commented out, which presumably causes a memory leak.
- Better makefile system that can put objects in different dirs.
- Extra wxBitmap formats: PNG, BMP. Could use old wxWin 1.68
wxImage code (derived from XV) for BMP/GIF but it's very bloated. However,
when implemented as extra bitmap handlers, the code won't be linked
unless needed. Update: see if wxImage can handle these formats.
- Print/preview framework in print.cpp (see wxGTK).
- Enhance event handling such that you override e.g. left-click
and unless you call the base OnMouseEvent, the click won't be
sent to the button. Required for Dialog Editor.
- Get Dialog Editor working under Motif.
- New wxHelp version: try using the XmHTML widget at
http://www.xs4all.nl/~ripley/XmHTML/.
We need to:
- make a minimal distribution under wx/src/xmhtml, just enough
to compile the source.
- add XMHTML_C_SRC to src/motif/makefile.unx with the source files
listed.
- make sure we can compile the sources, passing the correct
flags for zlib/png compilation.
- make a wxHTMLWindow class from e.g. examples/example_2.c. Should
probably make the cache and history facilities part of the class.
- add the driver code to src/motif/helphtml.cpp (a frame, toolbar,
history list).
- Copy and paste, drag and drop. Use a standard X drag
and drop standard - see http://www.cco.caltech.edu/~jafl/xdnd/
or use Motif drag and drop as described here:
http://www.motifzone.com/tmd/articles/DnD/dnd.html
- Optimize colour management so we don't get clashes when e.g.
Netscape is running. See:
http://www.motifzone.com/tmd/articles/John_Cwikla/index.html
- wxRCConfig (a config class using X .rc files). Could simply
implement it in terms of current wxGet/WriteResource functions.
- wxCheckBoxList
- wxBitmapCheckBox, wxBitmapRadioButton
- Reimplement combobox using Lesstif's widget (avoiding GPL'ed
widget currently used).
- Miscellaneous classes e.g. wxJoystick (identical to GTK's one for
Linux)
- Blit scaling
- Get ODBC classes and sample working.
- Work out why wxTextCtrl doesn't work as a stream buffer under
gcc
