  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 - Finish wxNotebook.
  39
  40 - wxSpinButton
  41
  42 - Tidy dialogs such as the colour and font selectors.
  43
  44 - Use generic wxTreeCtrl, wxListCtrl: debug and enhance these.
  45   We're close to having these working: mostly scrolling to work out.
  46
  47 - Find out why modal dialogs give a grab warning.
  48
  49 - wxSystemSettings. Eventually, should have control panel-like utility
  50   to change colours/fonts but meanwhile should maybe read them
  51   from a file.
  52
  53 - wxThread (hopefully, similar to wxGTK)
  54
  55 - wxGrid: scrollbars don't hide; problem with cell selection.
  56
  57 - MDI: seems to be broken for a more complex application I'm testing.
  58   Frame decorations don't draw properly, and a child window doesn't
  59   process events properly. So probably we should have an alternative
  60   implementation that uses tabs, a la wxGTK. The system menu could
  61   be implemented using a pop-up menu that applies to the currently
  62   active window.
  63
  64 - Controls in a wxToolBar don't work. Probably due to form layout
  65   problems; the workaround is to use a separate panel for controls.
  66
  67 - Miscellaneous events.
  68
  69 - Write makefiles for all samples and utilities.
  70
  71 - Create some samples for testing.
  72
  73 Low Priority
  74 ------------
  75
  76 - Better makefile system that can put objects in different dirs.
  77   Use wxGTK config system? It's really complex to debug and
  78   doesn't offer a way of compiling apps outside the wxWin
  79   hierarchy.
  80
  81 - Extra wxBitmap formats: PNG, BMP. Could use old wxWin 1.68
  82   wxImage code (derived from XV) for BMP/GIF but it's very bloated. However,
  83   when implemented as extra bitmap handlers, the code won't be linked
  84   unless needed.
  85
  86 - Print/preview framework in print.cpp (see wxGTK).
  87
  88 - Enhance event handling such that you override e.g. left-click
  89   and unless you call the base OnMouseEvent, the click won't be
  90   sent to the button. Required for Dialog Editor.
  91
  92 - Get Dialog Editor working under Motif.
  93
  94 - New wxHelp version: try using the XmHTML widget at
  95   http://www.xs4all.nl/~ripley/XmHTML/.
  96
  97   We need to:
  98   - make a minimal distribution under wx/src/xmhtml, just enough
  99     to compile the source.
 100   - add XMHTML_C_SRC to src/motif/makefile.unx with the source files
 101     listed.
 102   - make sure we can compile the sources, passing the correct
 103     flags for zlib/png compilation.
 104   - make a wxHTMLWindow class from e.g. examples/example_2.c. Should
 105     probably make the cache and history facilities part of the class.
 106   - add the driver code to src/motif/helphtml.cpp (a frame, toolbar,
 107     history list).
 108
 109 - Optimize screen refresh for non-native widgets, e.g. wxWindow
 110   created with Create(), using technique in flicker patch for 1.68
 111   (see JACS for latest patch).
 112
 113 - Copy and paste, drag and drop. Use a standard X drag
 114   and drop standard - see http://www.cco.caltech.edu/~jafl/xdnd/
 115   or use Motif drag and drop as described here:
 116   http://www.motifzone.com/tmd/articles/DnD/dnd.html
 117
 118 - Optimize colour management so we don't get clashes when e.g.
 119   Netscape is running. See:
 120   http://www.motifzone.com/tmd/articles/John_Cwikla/index.html
 121
 122 - wxRCConfig (a config class using X .rc files). Could simply
 123   implement it in terms of current wxGet/WriteResource functions.
 124
 125 - wxCheckBoxList
 126
 127 - wxBitmapCheckBox, wxBitmapRadioButton
 128
 129 - Reimplement combobox using Lesstif's widget (avoiding GPL'ed
 130   widget currently used).
 131
 132 - Write generic wxDirDialog (directory selector)
 133
 134 - Use native Motif dialogs for wxMessageBox
 135
 136 - Miscellaneous classes e.g. wxJoystick (identical to GTK's one for
 137   Linux)
 138
 139 - Blit scaling
 140
 141 - Could eventually alter the MDI widgets to be more Windows-like
 142   -- currently it's half-hearted (menus are on children, whereas
 143   they should replace the main parent frame menu).
 144
 145 - Get ODBC classes and sample working.
 146
 147 - Work out why wxTextCtrl doesn't work as a stream buffer under
 148   gcc
