wxWidgets 2.8.12 FreeBASIC C wrapper

MOD · Post by **MOD** » Jul 11, 2011 14:36

It's not good to break with old structures.

I think it's ok to make a OOP-wrap because it's on code-base in the header and don't affect the wrapper. Add new things to the wrapper will break the compatibility to the original wx-c and this may be a real problem for feature versions. A solution could be overloading the functions but with every new version of wx-c all the changes have to be done again.

For now I'll keep to the last version of the header. Thank you so far.

I don't understand you
why you will use the wrong version of wxEvtHandler ?

The addesss of the EventHandler callback was stored in the UserData property
and can be overwritten with your own UserData thats is an critical error:

and what are better ?

wxEvtHandler_proxy(MyButton, @MyEventListener)
wxEvtHandler_Connect(MyButton,EventType)

or the real wxWidget call

wxEvtHandler_Connect(MyButton,EventType,@MyEventHandler)

Again the wc-c project is dead you are talk about the wx.NET C wrapper
(and this wrapper is out of date wxWidget 2.6)

wx-c is part of WX.Net and the latest version is 0.9.2, based on wxWidgets 2.8. The last release was at 2010-07-14. It's just one year and it's not dead.

I want to use the lib provided with this release (at least the code of the bundle). This is what FreeBASICs header did and should do as long as we can't use wxWidgets without any wrapper.

Maybe their eventcall isn't the best solution, but changing it will break with the original code and will break a lot of codes written.

You're doing a wx-c 'fork'...

Or more logical to use the official wxwidgets to ensure future compatibility, well ok I get out ...

If i renember me right the first FreeBASIC wx-c headers was from wxc.sourceforge.net

Be open for new things in the world of IT things changing very often. :-)

I'm not a slave from any NET or MONO project we can have our own wxWidgets FB wrapper.

I added wxGLCanvas, wxTimer, wxSound and will add all the missing cool stuff TCPServer, TCPClient ... later.
I fixed some mistakes and made every class safer if(self!=NULL) and so one
i wrote a new 100% compatibe wxEvtHandler.

Now it's your turn would be cool if you support FreeBASIC with your wxDesigner.

http://www.freebasic.net/index.php/deta ... =lib&id=35

It's WX.Nets wrapper not wxc.

It is easier to have the Net-people which update the wrapper and only translate the header than when 1-2 people update a special FB-version.

If you want to provide this new methods maybe it would be an idea to split it up in two libs. The first one just uses the original wx-c methods, the second one the new methods.

Now I'm back at home and made some tests on linux
all works fine except "mdi01_wx-c.bas".
I don't know why but the ChildFrames are not shown ?

with "upx -9 wx-c.dll" the dll are 1.75MB

I saw that you asked what would be better (not really sure, I had no time to read it) and now it's edited. If it was about the lib: the best way to handle it would be, that the libs provided with wx.Net 0.9.2 would work with FB. This is not as easy because of the underscore in this version. Soon I'll have some sparetime and will look at this problem so that we get header for both windows and linux for this lib without having to compile it by yourself. Any further functions should be done with a second lib, a ext-wx-c-lib. I remember defines in your edited code (WX_CODE_ADVANCED). This could be added to the FB-header so that there will be no problems with the original version of the lib and just small fixes needed for new versions and provide additional functionality.

MOD you don't need to define anything
why you don't test the last version ?

after #include "inc/wx.bi" it's pure wx-c

all examples you posted works without any changes

MOD · Post by **MOD** » Jul 13, 2011 10:22

You maybe changed the eventhandling but it's not 'pure' wx-c. It's compiled by you (btw I'm not sure if you're allowed to add your name as an autor) with lots of functions, which are not included in the original version.

It's maybe nice to have this but what will happen if the wx.Net people change lot of things in the code? You'll have to do it all again.

(demo01_wx-c.bas isn't compiling properly and why this wxSound-info, this warnings are annoying.)

D.J.Peters · Post by **D.J.Peters** » Jul 13, 2011 23:52

Only in this one example the old wxEvtHandler_proxy() was missed.

I hope do you have fun with your destructive comments.

No, I think you missunderstood what I'm trying to say. I really appreciate what you've done, it's the first step to get the latest wx-c working with FB. But, everthing you're doing beyond the wx.Net version of wx-c, it's not wx-c anymore. It's a new wrapper for wxWidgets, call it wxFB or what you want, but it's not wx-c anymore.

I also really like your implementations for new widgets but my plan is to have compatible header and a compatible designer for the wx-c version included with wx.Net 0.9.2. This is my first aim, nothing more nothing less. When I'm at this point that their lib works with the designer I'll consider making a extended designer for your new wrapper. This will sure take some time but I think it's exactly what FB needs.

My suggestions:
- first rename the lib so it's clear that it's not wx-c from the wx.Net project
- implement all functions and everything what you thing it's a good idea
- make examples for everything what's beyond the original wx-c functionality

Then we can easily change the designers output and it will support your new lib.

I am trying to xrc for gui design and is at a loss how to get the update the controls such as checklistctrl.

In the below example when i use wxwindow functions to update the controls then they work. but if i try to use the control specific functions they fail.

In python I used to use "xrc.XRCCTRL" but i am not able to find any equivalent to that.

Any help will be great.
