   8 General comment: see the following site for useful Motif widgets.

  11 Also, grep for TODO comments in source.
  12
  13 High Priority
  14 -------------
  15
  16 - Work out why XFreeFont in font.cpp produces a segv. This is
  17   currently commented out, which presumably causes a memory leak.
  18
  19 - Also work out why wxWindow::SetFont causes the widget to be shrunk
  20   to fit its text, in dialogs. Uncomment the SetFont implementation and pop
  21   up a dialog, e.g. an About box. Widgets are arranged
  22   incorrectly. Seems to be OK for non-dialog panels, once the
  23   size has been restored after the font setting.
  24   In fact it seems OK for dialogs now!!! Weird.
  25
  26 - ChangeFont should have an extra arg, to allow for not resizing
  27   the window back to the original size after setting the font.
  28   Also don't call SetFont from constructor, assign the font and
  29   call ChangeFont so we can pass FALSE if the size has been passed
  30   as the default (which means: wxWin should choose an appropriate
  31   size, so Motif should expand/contract the widget as appropriate).
  32
  33 - Colour setting in widgets (almost done).
  34
  35 - Implementation of OnEraseBackground. How? Call OnEraseBackground
  36   just before OnPaint? Will duplicate Xlib's own erase of the background.
  37   However, this is usually OK, because the default wxWindow::OnEraseBackground
  38   can do nothing (SetBackgroundColour will make the background look OK).
  39   And if a custom OnEraseBackground uses the same colour as the window
  40   background, no flicker will be seen. If it does something else, such as
  41   painting a tiled bitmap, then a slight flicker might be seen unless
  42   X can be persuaded not to repaint the window background by default.
  43
  44 - wxSpinButton
  45
  46 - A generic version of wxNotebook that can be used in wxMotif and
  47   other toolkits that don't have a native control. Perhaps use wxTab as a
  48   starting point.
  49
  50 - Tidy dialogs such as the colour and font selectors.
  51
  52 - Use generic wxTreeCtrl, wxListCtrl: debug and enhance these.
  53
  54 - Find out why modal dialogs give a grab warning.
  55
  56 - wxSystemSettings. Eventually, should have control panel-like utility
  57   to change colours/fonts but meanwhile should maybe read them
  58   from a file.
  59
  60 - wxThread (hopefully, similar to wxGTK)
  61
  62 - Miscellaneous events.
  63
  64 - Write makefiles for all samples and utilities.
  65
  66 - Create some samples for testing.
  67
  68 Low Priority
  69 ------------
  70
  71 - Better makefile system that can put objects in different dirs.
  72   Use wxGTK config system? It's really complex to debug and
  73   doesn't offer a way of compiling apps outside the wxWin
  74   hierarchy.
  75
  76 - Extra wxBitmap formats: PNG, BMP. Could use old wxWin 1.68
  77   wxImage code (derived from XV) for BMP/GIF but it's very bloated. However,
  78   when implemented as extra bitmap handlers, the code won't be linked
  79   unless needed.
  80
  81 - Print/preview framework in print.cpp (see wxGTK).
  82
  83 - Enhance event handling such that you override e.g. left-click
  84   and unless you call the base OnMouseEvent, the click won't be
  85   sent to the button. Required for Dialog Editor.
  86
  87 - Get Dialog Editor working under Motif.
  88
  89 - New wxHelp version: try using the XmHTML widget at
  90   http://www.xs4all.nl/~ripley/XmHTML/.
  91
  92   We need to:
  93   - make a minimal distribution under wx/src/xmhtml, just enough
  94     to compile the source.
  95   - add XMHTML_C_SRC to src/motif/makefile.unx with the source files
  96     listed.
  97   - make sure we can compile the sources, passing the correct
  98     flags for zlib/png compilation.
  99   - make a wxHTMLWindow class from e.g. examples/example_2.c. Should
 100     probably make the cache and history facilities part of the class.
 101   - add the driver code to src/motif/helphtml.cpp (a frame, toolbar,
 102     history list).
 103
 104   Note that a quicker route to a help system may be to use the
 105   code in the contrib dir of XmHTML to control a Netscape session --
 106   but Netscape can be a colour resource hog.
 107
 108 - Optimize screen refresh for non-native widgets, e.g. wxWindow
 109   created with Create(), using technique in flicker patch for 1.68
 110   (see JACS for latest patch).
 111
 112 - Copy and paste, drag and drop. Use a standard X drag
 113   and drop standard - see http://www.cco.caltech.edu/~jafl/xdnd/
 114   or use Motif drag and drop as described here:
 115   http://www.motifzone.com/tmd/articles/DnD/dnd.html
 116
 117 - Optimize colour management so we don't get clashes when e.g.
 118   Netscape is running. See:
 119   http://www.motifzone.com/tmd/articles/John_Cwikla/index.html
 120
 121 - wxRCConfig (a config class using X .rc files). Could simply
 122   implement it in terms of current wxGet/WriteResource functions.
 123
 124 - wxCheckBoxList
 125
 126 - wxBitmapCheckBox, wxBitmapRadioButton
 127
 128 - Reimplement combobox using Lesstif's widget (avoiding GPL'ed
 129   widget currently used).
 130
 131 - Write generic wxDirDialog (directory selector)
 132
 133 - Use native Motif dialogs for wxMessageBox
 134
 135 - Miscellaneous classes e.g. wxJoystick (identical to GTK's one for
 136   Linux)
 137
 138 - Blit scaling
 139
 140 - Could eventually alter the MDI widgets to be more Windows-like
 141   -- currently it's half-hearted.
 142
 143 - Accelerators
 144
 145 - Get ODBC classes and sample working.
