wxSingleInstanceChecker message

[Ksawery]

Hello,

I'm using wxSingleInstanceChecker to ensure that only one instance of my application is running. It works fine, however sometimes I see a message stating "Deleted stale lock file 'home/.../AppName' ". I know that this message only appears when the app is terminated indirectly (e.g. by killing the process in the terminal, or in the IDE debugger). I understand that it doesn't affect the execution of the app, and is useful for debugging purposes, however it won't be understandable to the end-user. Is there a way to suppress this message, or avoid it altogether?

I'm not sure if it works here, but try wrapping the creation of the wxSingleInstanceChecker instance with wxLogNull:

Thank you, it worked! I used the following code:

Code: Select all

{
wxLogNull logNo;
wxChecker = new wxSingleInstanceChecker(_T("PomiarWiazki"));
}

Two more things - i'm seeing the following message in the console:

Code: Select all

Gtk-Message: 10:43:55.126: GtkDialog mapped without a transient parent. This is discouraged.

Is this something to be concerned about? This message also pops up in the terminal, and might be confusing to the end-user. It only occurs when attempting to start the application, when one session is already running.

Secondly, can I change the title of an error window? For example, the following window:

Thank you very much for your help!

Secondly, can I change the title of an error window? For example, the following window:

Is this an internal error message from wxWidgets or is it something you open in your code? If you use wxMessageBox, there is an additonal parameter for the caption.

If it's an internal error message, it probably uses the application name set by wxApp::SetAppName()

I'm using wxLogError() to display the message, after checking if another instance is already running:

Code: Select all

if (wxChecker->IsAnotherRunning())
{
    wxLogError(_T("\nProces już istnieje!"));
    delete wxChecker; // OnExit() won't be called if we return false
    wxChecker = NULL;
    return false;
}

Using wxApp::SetAppName() helped set the title of the error window, thanks.

How about the GTK message, is there a way to suppress it or avoid it? It only pops up when displaying the error window.

Edit: I tried using wxMessageBox instead of wxLogError, and i'm still seeing the gtk message.

Is it debug or release mode?
