Re: [wxhaskell-devel] Property sheet
Hi Dave, Playing catch-up after the weekend... Short answer - I think you have the correct places to put code.

Dave, In my quest to understand how a class from wxWidgets is wrapped I took at look at wxSlider as it shares the same class hierarchy as wxPropertyGrid and 'slider' is a fairly distinct term. Searching for 'slider' in the wxHaskell code I extracted the following references to it. Does this look complete? If anyone could comment further on what function each part provides I'd be very grateful. # HAND-WRITTEN FILES # ./wx/src/Graphics/UI/WX/Controls.hs: Haskell impl 'High' level Haskell wrapper. You place constructors which are property-aware here. In most respects this is straightforward except that you need to work out what instances are appropriate to a PropertyGrid. You may want to look at http://wewantarock.wordpress.com/2010/01/11/custom-controls-in-wxhaskell-part-3/for some more information about implementing Attribute instances. ./wxcore/src/eiffel/wx_defs.e: Eiffel alias for wxEVT_COMMAND_SLIDER_UPDATED as expEVT_COMMAND_SLIDER_UPDATED An ugly piece of legacy from the days when wxcore was derived from an Eiffel wrapping of wxWidgets. Event identifiers need to be defined here. I *really* want to get rid of this file one day - it serves no purpose to have an Eiffel file these days. ./wxcore/src/include/wxc.h: TClassDefExtend saying wxSlider95 and wxSliderMSW are wxSlider This creates the correct type witnesses to map the class Hierarchy. ./wxcore/src/include/wxc_glue.h: Decl of int expEVT_COMMAND_SLIDER_UPDATED(); TClassDefExtend saying wxSlider is a wxControl Decl of many wxSlider_ methods such as wxSlider_ClearSel Decl of wxXmlResource_GetSlider method This is basically where you need to put the declarations for C++ method wrappers. ./wxcore/src/haskell/Graphics/UI/WXCore/Layout.hs: This code is commented out I don't think you would need to do anything here ./wxcore/src/haskell/Graphics/UI/WXCore/Events.hs: Exports sliderOnCommand, sliderGetOnCommand Def for sliderOnCommand which sends wxEVT_COMMAND_SLIDER_UPDATED and take an eventHandler Def for sliderGetOnCommand which returns the event handler Your Haskell event handler code goes here. You need one function which reacts to events, which accepts an event handler as a parameter and a function which will fetch your event handler (you need this mostly in case you want to hook a further event handler which doesn't kill the one already present). ./wxcore/src/cpp/extra.cpp: ifdef wxUSE_SLIDER wxT(SLIDER) I'm not completely sure why this is required. I suspect it's not used any more. ./wxcore/src/cpp/eljslider.cpp: EWXWEXPORT calls for all the wxSlider_ methods decl'd in wxc_glue.h Implementations of the wrappers. The old eljXXX naming convention for these files really isn't necessary any more. I'd suggest calling the implementation 'propertysheet.cpp' or something like that. ./wxcore/src/cpp/eljrc.cpp: BUILD_XRCGETCTRL_FN(Slider) (constructs functions for geting control pointers out of window hierarchies created from XRC files. The functions themselves) Correct. ./wxcore/src/cpp/defs.cpp:EWXWCONSTANTINT(wxEVT_COMMAND_SLIDER_UPDATED,wxEVT_COMMAND_SLIDER_UPDATED) I'd forgotten about these. Another way of wrapping up event values as functions. I don't tend to do this, and I don't think anyone has for years... ./wxcore/src/cpp/eljevent.cpp: MAKE_EVENT_WRAPPER(EVT_COMMAND_SLIDER_UPDATED) I tend to do this instead. It does exactly the same thing as the code in defs.cppp. # MISC FILES # ./wxcore/wxcore.cabal: add src/cpp/eljslider.cpp to c-sources Obvious... ./samples/test/XRCControls/XRCControls_Wx.hs: test code for xrc You should probably write one or more pieces of test code for your wrapped control. # GENERATED FILES # ./wxcore/src/haskell/Graphics/UI/WXCore/WxcClassesMZ.hs: File generated by wxDirect from ./wxcore/src/include/wxc.h: Export of (wxEVT_COMMAND_SLIDER_UPDATED :: EventId) Export of many slider functions such as sliderClearSel, these match the wxSlider_ methods decl'd in wxc_glue.h Export of xmlResourceGetSlider function decl'd in wxc_glue.h Definition for slider functions using FFI foreign import ccall Definition of wxEVT_COMMAND_SLIDER_UPDATED which imports the enum value Definition of xmlResourceGetSlider using FFI foreign import ccall ./wxcore/src/haskell/Graphics/UI/WXCore/WxcClassInfo.hs: File generated by wxDirect Export of classSlider, classSlider95, classSliderMSW Export of downcastSlider, downcastSlider95, downcastSliderMSW Definition classSlider functions which bind them to the their C++ class names using a
