################ the last time working on ################
Bug:
- BROKEN $canvas->cdDumpBitmap("tmp-testoutput.png", "PNG"); - tmp-testoutput.png / examples/2-canvas/simpledraw.pl
IupMatrixEx - add new element - http://www.tecgraf.puc-rio.br/iup/en/ctrl/iupmatrixex.html
- IUP::MatrixEx? or maybe extend existing IUP::Matrix?
- callbacks
- IupMatrixExOpen() void IupMatrixExOpen(void);
- calling IupMatrixExInit for an existing IupMatrix control. void IupMatrixExInit(Ihandle* ih);
fix:
- cb_table->{_dragdrop} what about CanvasGL, PPlot, MglPlot ?
- cb_table->{_canvas} what about PPlot, MglPlot ?
- global callbacks
##########################################################
######## later
- Canvas: void functions should return $self
- implement: MglPlotSetData(Ihandle *ih, int ds_index, float* data, int count_x, int count_y, int count_z);
- POD: IUP::Canvas::FileBitmap: Supported constructors: XXX-TODO add some description
- POD: IUP::Canvas::FileVector: Supported formats: XXX-TODO more description
- POD: overall "doc polish" needed - search for 'XXX'
- POD: html tables - metacpan.org breaks header line (probably broken <th>)
######## CODE/IMPORTANT: correct element destruction still needs some work
- Internal/Element.pm (look for XXX-FIXME + XXX-CHECKLATER)
######## TESTS/IMPORTANT: add more tests
- split tests: t\*.t + all GUI-related >>> t\gui\*.t
- maybe close after timeout (IUP::Timer -> return IUP_CLOSE)
- how to skip - example:
plan skip_all => "\$ENV{RELEASE_TESTING} required fot testing", unless $ENV{RELEASE_TESTING};
eval "use Win32::Job ()";
plan skip_all => "Can't interrupt hung processes without Win32::Job" if $@;
######## POD/COSMETICS: mention in POD/DOC
- mention IUP::Manual::10_FAQ::PARPacking recommendation in DOC
- beware: (IUP_DEFAULT related) sub returns value even without explicit return
- pplot: note in doc that DS_ has to be set after ->PPlotEnd()
- tree: note in doc that tree->SetAttribute has to go after dialog->Show
######## MAYBE: access child=>[...] items like this
$mybox = IUP::Hbox->new( child=>[ $bt1, $bt2, $bt3] );
$mybox->[0]->FGCOLOR("255 0 0"); # changes bt1 foreground color
$mybox->[1]->FGCOLOR("255 0 255"); # changes bt2 foreground color
- beware: somehow handle AddChild & co.
- from perl doc:
$a = $array[5]; $obj->FETCH(5);
$array[5] = "aa" $obj->STORE(5, "aa");

### COSMETICS ################################################################################################
(cosmetics)######## NICE-TO-HAVE: cdKillCanvas
- see examples/2-canvas/simpledraw.pl
- why we need 'undef $canvas' and '$canvas->cdKillCanvas()' is not enough?
(cosmetics)######## NICE-TO-HAVE: more Canvas examples
- port more lua examples into perl
(cosmetics)######## IDEA:
use IUP qw/:basic iup_NO_INIT/; #generally iup_ANY_OTHER_FLAG
(cosmetics)######## IUP::Canvas missing functions (not crutial for now)
- void wdCanvasHardcopy(cdCanvas* canvas, cdContext* ctx, void *data, void(*draw_func)(cdCanvas *canvas_copy));
- int cdContextRegisterCallback(cdContext *context, int cb, cdCallback func);
- void cdInitContextPlus(void); /* needs: GDI+, Cairo, XRender */
(cosmetics)######## GTK too noisy when no DISPLAY: asck scuri
- GTK + no DISPLAY set - error during gtk_init_check (= during 'use IUP'):
(<unknown>:7541): GLib-GObject-CRITICAL **: g_object_unref: assertion `G_IS_OBJECT (object)' failed
IUP->Open == -1
[http://developer.gnome.org/doc/API/2.2/gtk/gtk-General.html]
bool XDisplayExists() {
return (gdk_display_get_default() != NULL);
}
++ if (!gdk_display_get_default ()) {
++ if (!gtk_init_check (NULL, NULL)) {
++ /* Oh well, no X for you! */
++ g_printerr (_("Unable to connect to the X server"));
++ g_printerr ("%s", message);
++ exit (1);
++ }
++ }
++
- GTK/NOT-WORKING-DISPLAY
The application '<unknown>' lost its connection to the display localhost:10.0;
most likely the X server was shut down or you killed/destroyed
the application.
(cosmetics)######## global
- icon - see y:\IUP3.3\fltk\FLTK-0.532007\inc\MBX\FLTK.pm (ACTION_code)
(cosmetics)######## Check this:
- consider return; vs. return undef;
return IUP::Internal::LibraryIup::_voidfunc; == return;
return IUP::Internal::LibraryIup::_nonvoidfunc; == return undef;
SUGGESTION: always call: return IUP::Internal::LibraryIup::_func; (even for void functions)
- http://stackoverflow.com/questions/3435122/whats-the-difference-between-return-and-return-undef-in-perl
- "Perl Best Practices" (and Perl::Critic) suggest not using return undef
(cosmetics)######## IUP (main module)
- ??? better detection of initialized gui than (IUP->Open == IUP_OPENED)?
- ??? detection of codepage used in GUI
(cosmetics)######## IUP::Submenu
- consider using $firstonly param of new()
(cosmetics)######## IUP::ProgressBar
- FGCOLOR seems to be ignored
(cosmetics)######## IUP::Split
- maybe support also new($child1, $child2) instead of new(child1=>$child1, child2=>$child2)
(cosmetics)######## IUP::Internal::Element
- change: _create_element should set $self->ihandle value
### NOT NOW, MAYBE LATER ################################################################################################
(not now, maybe later)!!Big Task!! ######## IUP::OLE (extra module)
- $o->IUNKNOWN ... pointer created by CoCreateInstance Function http://msdn.microsoft.com/en-us/library/ms686615%28v=vs.85%29.aspx
- perahps integrate with Win32::OLE like $o->ole->methodname(...)
- Win32::OLE needs something like new_from_iunknown
IUnknown *punk = ... value from $olecontrol->IUNKNOWN;
HRESULT hr;
IDispatch *pDispatch = NULL;
hr = punk->QueryInterface(IID_IDispatch, (void**)&pDispatch);
punk->Release();
ST(0) = CreatePerlObject(aTHX_ stash, pDispatch, destroy);
- see Wx+OLE/ActiveX integration http://search.cpan.org/~mdootson/Wx-ActiveX-0.15/lib/Wx/ActiveX.pm
- missing example: notepad.wlua? olecontrol_browser.wlua?
- missing -> add
- conditionally only on Win32
- we probably need IUP::ConfigData for listing available features (iupole, iupgl ...)
(not now, maybe later)######## implement threads demo
- threads+Wx - http://use.perl.org/~Alias/journal/40377
(not now, maybe later)######## memory issues
- moustly should be handled, some corner cases may occur
- see http://stackoverflow.com/questions/2223721/common-perl-memory-reference-leak-patterns
- somehow check memory leaks - http://use.perl.org/~jozef/journal/40411
- somehow check memory consumption - Devel::Size, Devel::Peak, PerlBench
- http://stackoverflow.com/questions/1359771/perl-memory-usage-profiling-and-leak-detection
- http://www252.pair.com/comdog/mastering_perl/Chapters/06.benchmarking.html
- check memleaks by storing SetAttribute("ATTR", $ref)
(not now, maybe later)######## unicode in filenames (cpodepage magic)
http://www.i-programmer.info/programming/other-languages/1973-unicode-issues-in-perl.html
(not now, maybe later)######## missing examples
- no example for: Clipboard.pm ?
- no example for: User.pm ?
- no example for: ColorDlg.pm ?
- no example for: FontDlg.pm ?
(not now, maybe later)######## Linux - platform specific issues
- GTK: 'Quit' in main menu requires double click
### REJECTED FOR NOW ################################################################################################
