wxCrafter generated code using variables (wxSpinCtrl)?

[imalipusram]

Dear experts,

I am trying to set up a wxSpinCtrl where the minimum, maximum and default values are set by variables (g_default, g_min, g_max, see the code snippet below. I currently have them in a file global.cpp, later they will be read from a configuration file). wxCrafter is accepting the variables, but in order to compile the generated code, I manually have to edit wxcrafter.cpp (which I am not supposed to do ) and insert a line pointing to the header file to be included ("#include global.h") to make it compile and work. Of course, after the next edit of the GUI, this will be gone.

For illustration, the code generated by wxCrafter looks like this:

Code: Select all

m_spinCtrl = new wxSpinCtrl(m_panel, wxID_ANY, wxT("g_default"), wxDefaultPosition, wxSize(-1,-1), wxSP_ARROW_KEYS);
    m_spinCtrl->SetRange(g_min, g_max);
    m_spinCtrl->SetValue(0); 

In addition (as wxT("g_default") already might suggest), the default value is not taken from the variable g_default, but instead "1" is used.

Any suggestions how one could solve these problems, e.g. is there a way to make wxCrafter automatically include some lines of user code into generated code for the GUI? Or do I simply follow the wrong approach (being still pretty new to C++, wxWidgets, CodeLite and wxCrafter).

Many thanks for your help and suggestions!

What you should be doing is sublcassing wxSpinCtrl (e.g MySpin) note that your subclass should have the same ctor signature as descrbibed in wxWidgets docs http://docs.wxwidgets.org/stable/classw ... 583fa13c0f

Once you did this, in wxCrafter you should be using the "Subclass" field to set the your subclass name and include file.
See attached screenshot to see how I did similar thing with relacing wxAuiNotebook -> Notebook

In your sublclass write all your custom code that you need

Thanks, eranif!

Just found a rather quick (and probably becoming rather dirty when used more than once in a project, as the same header file would be included several times then) workaround is simply to include "global.h" (in my example) in the subclass section and use the abovementioned variable names as min an max in the control specific settings.


Best regards!

Dear Experts,

despite the previously posted workaround, I am trying to make it work the orthodox way, i.e. deriving a class from wxSpinCtrl. I have spent two days now fighting with the internet and lots of c++ resources, but I simply don't get any clue: I've been searching for advice on "subclassing wxSpinCtrl", "cpp inheritance", "derived class example" etc. and I am getting lost in the the lots of information I get: There are so many examples with and without header files and so many flavors of programming that I simply "can't see the see the forest because of the many trees" (German proverb).

Would anybody please be so inclined to point me to a resource that is teaching me what I really need to do to derive my own class from wxSpinCtrl and how I can tell it that I want to set the min, max and default values to my desires (with separate .h and .cpp files) or maybe just giving me an example?

Sorry, I am completely confused now, lots of thanks for your efforts!

Thank you!

Hi
wxWidgets Component Writing forum is probably a good place to post your question.
