  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 - Colour setting in widgets (almost done). Should scrollbars take
  20   on the background colour? Not right for e.g. wxScrolledWindows,
  21   so maybe have wxSystemSettings value for scrollbar colour, and/or
  22   ability to set scrollbar colour independently.
  23
  24 - Optimize wxWindow OnPaint to avoid flicker, collapsing Expose events
  25   as per flicker fix in 1.68. It will be tricky to avoid
  26   interfering with non-wxScrolledWindow widgets except by
  27   explicitly testing for wxScrolledWindow.
  28
  29 - Implementation of OnEraseBackground. How? Call OnEraseBackground
  30   just before OnPaint? Will duplicate Xlib's own erase of the background.
  31   However, this is usually OK, because the default wxWindow::OnEraseBackground
  32   can do nothing (SetBackgroundColour will make the background look OK).
  33   And if a custom OnEraseBackground uses the same colour as the window
  34   background, no flicker will be seen. If it does something else, such as
  35   painting a tiled bitmap, then a slight flicker might be seen unless
  36   X can be persuaded not to repaint the window background by default.
  37
  38 - wxNotebook bug: why doesn't the notebook sample appear until the
  39   user resizes the window again? But it's OK for MDI. Strange.
  40
  41 - wxSpinButton
  42
  43 - Tidy dialogs such as the colour and font selectors.
  44
  45 - Use generic wxTreeCtrl, wxListCtrl: debug and enhance these.
  46   We're close to having these working: mostly scrolling to work out.
  47
  48 - Find out why modal dialogs give a grab warning.
  49
  50 - wxSystemSettings. Eventually, should have control panel-like utility
  51   to change colours/fonts but meanwhile should maybe read them
  52   from a file.
  53
  54 - wxThread (hopefully, similar to wxGTK)
  55
  56 - wxGrid: scrollbars don't hide; problem with cell selection.
  57
  58 - MDI: seems to be broken for a more complex application I'm testing.
  59   Frame decorations don't draw properly, and a child window doesn't
  60   process events properly. So probably we should have an alternative
  61   implementation that uses tabs, a la wxGTK. The system menu could
  62   be implemented using a pop-up menu that applies to the currently
  63   active window.
  64
  65 - Controls in a wxToolBar don't work. Probably due to form layout
  66   problems; the workaround is to use a separate panel for controls.
  67
  68 - Miscellaneous events.
  69
  70 - Write makefiles for all samples and utilities.
  71
  72 - Create some samples for testing.
  73
  74 Low Priority
  75 ------------
  76
  77 - Better makefile system that can put objects in different dirs.
  78   Use wxGTK config system? It's really complex to debug and
  79   doesn't offer a way of compiling apps outside the wxWin
  80   hierarchy.
  81
  82 - Extra wxBitmap formats: PNG, BMP. Could use old wxWin 1.68
  83   wxImage code (derived from XV) for BMP/GIF but it's very bloated. However,
  84   when implemented as extra bitmap handlers, the code won't be linked
  85   unless needed.
  86
  87 - Print/preview framework in print.cpp (see wxGTK).
  88
  89 - Enhance event handling such that you override e.g. left-click
  90   and unless you call the base OnMouseEvent, the click won't be
  91   sent to the button. Required for Dialog Editor.
  92
  93 - Get Dialog Editor working under Motif.
  94
  95 - New wxHelp version: try using the XmHTML widget at
  96   http://www.xs4all.nl/~ripley/XmHTML/.
  97
  98   We need to:
  99   - make a minimal distribution under wx/src/xmhtml, just enough
 100     to compile the source.
 101   - add XMHTML_C_SRC to src/motif/makefile.unx with the source files
 102     listed.
 103   - make sure we can compile the sources, passing the correct
 104     flags for zlib/png compilation.
 105   - make a wxHTMLWindow class from e.g. examples/example_2.c. Should
 106     probably make the cache and history facilities part of the class.
 107   - add the driver code to src/motif/helphtml.cpp (a frame, toolbar,
 108     history list).
 109
 110 - Optimize screen refresh for non-native widgets, e.g. wxWindow
 111   created with Create(), using technique in flicker patch for 1.68
 112   (see JACS for latest patch).
 113
 114 - Copy and paste, drag and drop. Use a standard X drag
 115   and drop standard - see http://www.cco.caltech.edu/~jafl/xdnd/
 116   or use Motif drag and drop as described here:
 117   http://www.motifzone.com/tmd/articles/DnD/dnd.html
 118
 119 - Optimize colour management so we don't get clashes when e.g.
 120   Netscape is running. See:
 121   http://www.motifzone.com/tmd/articles/John_Cwikla/index.html
 122
 123 - wxRCConfig (a config class using X .rc files). Could simply
 124   implement it in terms of current wxGet/WriteResource functions.
 125
 126 - wxCheckBoxList
 127
 128 - wxBitmapCheckBox, wxBitmapRadioButton
 129
 130 - Reimplement combobox using Lesstif's widget (avoiding GPL'ed
 131   widget currently used).
 132
 133 - Write generic wxDirDialog (directory selector)
 134
 135 - Use native Motif dialogs for wxMessageBox
 136
 137 - Miscellaneous classes e.g. wxJoystick (identical to GTK's one for
 138   Linux)
 139
 140 - Blit scaling
 141
 142 - Could eventually alter the MDI widgets to be more Windows-like
 143   -- currently it's half-hearted (menus are on children, whereas
 144   they should replace the main parent frame menu).
 145
 146 - Get ODBC classes and sample working.
 147
 148 - Work out why wxTextCtrl doesn't work as a stream buffer under
 149   gcc
