wxValidator in wxCrafter

[marcelinux]

Hi.
I need a litle help, please.
I would like include a validator in a wxTextCtrl created by wxCrafter.
Seeing validate sample i found:

Code: Select all

    m_numericTextDouble = new wxTextCtrl
                              (
                                this,
                                wxID_ANY,
                                "",
                                wxDefaultPosition,
                                wxDefaultSize,
                                wxTE_RIGHT,
                                wxMakeFloatingPointValidator
                                (
                                    3,
                                    &g_data.m_doubleValue,
                                    wxNUM_VAL_THOUSANDS_SEPARATOR |
                                    wxNUM_VAL_NO_TRAILING_ZEROES
                                )
                              );

And it works, of course.

But I don’t know how make in wxCrafter.
I tryed this:
In the wxTextCtrl’s attributes there is a Subclass combo.
Herein, I input:
Class Name: wxTextCtrl
Include File: globalNum.h
Style: wxTE_RIGTH, wxMakeFloatingPointValidator(2, &g_valueFloat, wxNUM_VAL_THOUSANDS_SEPARATOR | wxNUM_VAL_NO_TRAILING_ZEROES )

Then, I add globalNum.h file in the project with:

Code: Select all

#include “wx/valnum.h”
// Global variable for wxMakeFloatingValidator
float g_valueFloat;

Resulting a compiling error:

Code: Select all

Please, where can I find an example?

Thanks.

My environment:
OS debian stretch 64bits
g++ (Debian 5.3.1-14) 5.3.1 20160409
wxWidgets 3.1.0 self compiled
CodeLite 9.1.5 binary package

You should change it to:

Code: Select all

extern float g_valueFloat;

and place the *definition* in a .cpp file (not in a header)

Great!
Thank you!
Now, I need to know whats flags can I apply.
I'll look for in http://docs.wxwidgets.org/3.0/classwx_validator.html

[marcelinux]

I have made a little tutorial to explain this solution.
I would like if a moderator could review it and, if would be of interest, please say me how must I send it.
Thank you.

You can attach it here as a text document and I will update the wiki pages
