wxFrame icon

Post by pixsta » Fri Mar 24, 2006 6:17 pm

Hello!

I want to add a icon to my wxframe:

Code: Select all

wxIcon wxicon; 
wxicon.LoadFile("icon.png",wxBITMAP_TYPE_PNG); // returns false everytime
myframe->SetIcon(wxicon);
The problem is, that "LoadFile" returns false. I also tried it with a gif. The size of the png is 32x32x24.

Thank you,

Did you call wxInitAllImageHandlers() in your app before setting your frame icon?

PNG isn't supportet by wxIcon, neither jpg etc.

Read the Manual ;)

I've had the same problem in the past. I believe I ended up being forced to use an XPM as that was the only format I could get to work. wxWidgets seems to have some real problems reguarding icons and especially reading stuff from Resource Files.

Here's the syntax I used for mine:

Code: Select all

#include "myicon.xpm" // at the top

// In the code
frame->SetIcon(wxIcon(myicon_xpm));

I use a .ico file referenced in a .rc file:

Code: Select all

FRAME_ICON             ICON                    "res\\app.ico"
and in my main frame constructor:

Code: Select all

#ifdef __WXMSW__
	wxIcon	icon;
	icon.LoadFile (wxT("FRAME_ICON"), wxBITMAP_TYPE_ICO_RESOURCE);
	SetIcon(icon);
#endif
It works well.

It works well.
Instead of having the #ifdef... check what the docs say:
A macro, wxICON, is available which creates an icon using an XPM on the appropriate platform, or an icon resource on Windows.

wxIcon icon(wxICON(mondrian));

// Equivalent to:

#if defined(__WXGTK__) || defined(__WXMOTIF__)
wxIcon icon(mondrian_xpm);
#endif

#if defined(__WXMSW__)
wxIcon icon("mondrian");
#endif

According to me, Using xpm file for icon is more easy.
