  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
  46 - Find out why modal dialogs give a grab warning.
  47
  48 - wxSystemSettings. Eventually, should have control panel-like utility
  49   to change colours/fonts but meanwhile should maybe read them
  50   from a file.
  51
  52 - wxThread (hopefully, similar to wxGTK)
  53
  54 - wxGrid: scrollbars don't hide; problem with cell selection.
  55
  56 - MDI: seems to be broken for a more complex application I'm testing.
  57   Frame decorations don't draw properly, and a child window doesn't
  58   process events properly. So probably we should have an alternative
  59   implementation that uses tabs, a la wxGTK. The system menu could
  60   be implemented using a pop-up menu that applies to the currently
  61   active window.
  62
  63 - Controls in a wxToolBar don't work. Probably due to form layout
  64   problems; the workaround is to use a separate panel for controls.
  65
  66 - Miscellaneous events.
  67
  68 - Write makefiles for all samples and utilities.
  69
  70 - Create some samples for testing.
  71
  72 Low Priority
  73 ------------
  74
  75 - Better makefile system that can put objects in different dirs.
  76   Use wxGTK config system? It's really complex to debug and
  77   doesn't offer a way of compiling apps outside the wxWin
  78   hierarchy.
  79
  80 - Extra wxBitmap formats: PNG, BMP. Could use old wxWin 1.68
  81   wxImage code (derived from XV) for BMP/GIF but it's very bloated. However,
  82   when implemented as extra bitmap handlers, the code won't be linked
  83   unless needed.
  84
  85 - Print/preview framework in print.cpp (see wxGTK).
  86
  87 - Enhance event handling such that you override e.g. left-click
  88   and unless you call the base OnMouseEvent, the click won't be
  89   sent to the button. Required for Dialog Editor.
  90
  91 - Get Dialog Editor working under Motif.
  92
  93 - New wxHelp version: try using the XmHTML widget at
  94   http://www.xs4all.nl/~ripley/XmHTML/.
  95
  96   We need to:
  97   - make a minimal distribution under wx/src/xmhtml, just enough
  98     to compile the source.
  99   - add XMHTML_C_SRC to src/motif/makefile.unx with the source files
 100     listed.
 101   - make sure we can compile the sources, passing the correct
 102     flags for zlib/png compilation.
 103   - make a wxHTMLWindow class from e.g. examples/example_2.c. Should
 104     probably make the cache and history facilities part of the class.
 105   - add the driver code to src/motif/helphtml.cpp (a frame, toolbar,
 106     history list).
 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 (menus are on children, whereas
 142   they should replace the main parent frame menu).
 143
 144 - Get ODBC classes and sample working.
