Title: Problem with wxSmith
Post by: killerbot on November 01, 2005, 06:52:06 pm

When I am designing my GUI of my plug-in, I am using the wxSmith to do this.
My dialog has a wxBoxSizer, which in turn contains a wxStaticBoxSizer.
My goals is to change the label at runtime of the staticBoxSizer (?if this is possible?), I first started out with constructs like :
m_Comments = XRCCTRL(*this, "ID_TEXTCTRL_COMMENTS", wxTextCtrl)->GetValue();
This one is for a textctrl, but when I try this for the sizer it fails.

So , let's try to make it a member of the dialog and see what we can do then.
BUT when in wxSmith I make my wxBoxSizer (or my wxStaticBoxSizer) a member, wxSmith creates code in the constructor of the dialog like this :
BoxSizer1 = XRCCTRL(*this,"",wxBoxSizer);
But that does not compile, I get the following error on that line :
Ccdialog.cpp:15: error: invalid static_cast from type `wxWindow*' to type `const wxBoxSizer*'

Bug in wxSmith or am I doing something wrong ?
I know that wxSizer does not derive from wxWindow, so maybe the whole construct created is illegal ?

Any ideas welcome,
many thanks,
Lieven

Yes, a sizer is an object *attached* to a wxWindow. You might find the wxWidgets manual useful. Also, try taking a look at some of the XRC files for codeblocks.

Conclusion is therefor : bug in wxSmith !

It should not generate code like this, or don'y even allow the sizer to be a member. Probably member might be ok, but other code to retrieve the object is needed.

This has already been fixed :)

Using XRC You can only get wxWindow-derived items. XRC headers doesn't even have macros for other objects (like sizers).
I see two solutions here:

* First is to use wxSmith's automatically generated code (without XRC file) but I guess it won't sattisfy You, or
* use GetSizer() to get wxStaticBoxSizer object from widget containing this sizer, next call GetStaticBox from this sizer and then try SetLabel() on wxStaticBox. It worked for me :)

Can we already download a new 'dll' binary with the fixes of wxSmith ?

Another question :

the dialog has several sizers, how to you "GetSizer" the correct one ??

For example : I need the "StaticBoxSizer1"

<object class="wxDialog" name="CcDialog">
<title>ClearCase Plug-in for Code::Blocks</title>
<style>wxCAPTION|wxTHICK_FRAME|wxSYSTEM_MENU|wxCLOSE_BOX</style>
<object class="wxBoxSizer" variable="BoxSizer1" member="no">
<orient>wxVERTICAL</orient>
<object class="sizeritem">
<option>1</option>
<border>5</border>
<flag>wxALL|wxALIGN_CENTER|wxEXPAND</flag>
<object class="wxStaticBoxSizer" variable="StaticBoxSizer1" member="no">

<flag>wxALL|wxALIGN_CENTER|wxEXPAND</flag>
<object class="wxStaticBoxSizer" variable="StaticBoxSizer1" member="no">

OK, let's see, it would be something like this (Haven't tested that but it should be working ;) ):

Code

wxSizer* MainSizer = GetSizer(); // Getting BoxSizer1 item
wxStaticBoxSizer* Sizer = (wxStaticBoxSizer*)( MainSizer->GetItem(0)->GetSizer() );
wxStaticBox* Box = Sizer->GetStaticBox();
Box->SetLabel(_("Anything You want :)"));

(I would add some NULL checks, one small XRC file change and C::B crashes.)

Maybe new dll will be included in next binary snapshot by ceniza (http://gda.utp.edu.co/~ceniza/CodeBlocks/). But I really don't know when it will be ;)
