wxSmith question Window styles

[tigerbeard]

I have a wxSmith managed wxFrame with a constructor like this

Code Select Expand

MyFrame::MyFrame( wxWindow* parent, bool bNoBorder )
{
...
//(*Initialze(Myframe)
Create( parent, id, wxEmptyString, wxDefaultPosition, wxDefaultSize, wxDEFAULT_FRAME_STYLE|wxBORDER_NONE );
...
}

wxSmith hardcodes the window styles  from the wxSmith property page checkbox where I can select or unselect wxBORDER_NONE. Above its selected. The selection is at compile time. The variable can only be set during window create, so i can not set it later.

How can I still use wxSmith and control the wxBORDER_NONE style by my variable "bNoBorder"?

Go to the "Resources" tab in the C::B management pane. Navigate to your frame class and click it. Scroll down, find and expand the "Style" setting. wxBORDER_NONE is one of many you can enable/disable.

Hi, I think this method is "manually configure the option", and the style value is fixed(constant) after you tweak the wxSmith setting.

What tigerbeard want is a flexiable way, which means the "bool bNoBorder" should be passed to the "Create()" function call.

I don't find a better way to do that inside the wxSmith. But you can use a hack.

For example,

Code Select Expand


MyFrame::MyFrame( wxWindow* parent, bool bNoBorder )
{

#define wxDEFAULT_FRAME_STYLE bNoBorder // change the wxDEFAULT_FRAME_STYLE to bNoBorder

...
//(*Initialze(Myframe)
Create( parent, id, wxEmptyString, wxDefaultPosition, wxDefaultSize, wxDEFAULT_FRAME_STYLE );
...
}



Hopefully you don't use any wxDEFAULT_FRAME_STYLE in the following code in the same cpp file.

Or, you can use a better way, you can just restore the macro definition later, see this post: Temporarily overwrite a macro in C preprocessor - Stack Overflow

Hope that helps.

Another possibility is to change the style after frame creation, I don't know if it works for all styles, but here is an event handler that changes the frame style at runtime. It workes on both Windows and Linux

Code Select Expand

void Uview2dFrame::OnStayOnTopCheckBoxClick(wxCommandEvent& event)
{
   int style = GetWindowStyle();
   if(event.IsChecked())SetWindowStyle(style | wxSTAY_ON_TOP);
   else                 SetWindowStyle(style & ~wxSTAY_ON_TOP);
   Refresh();
}
It could well be this is not universally working for all styles though.

thats why i wrote

That is a pretty nice idea, very helpful. A you say its qute a mess but when used in rare cases and when its documented well in the code that should be fine.!
Thanks a lot
