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