Button label centering with GTK+2

[raananb]

Tried different sequences, but no improvement. I did notice that the problem
is present with the larger font even if it is normal (not bold).

First try:

// existing code

    gtk_button_set_label(GTK_BUTTON(m_widget), wxGTK_CONV(labelGTK));  
    gtk_button_set_use_stock(GTK_BUTTON(m_widget), FALSE);

// added code

    float x_alignment = 0.5;
    if (HasFlag(wxBU_LEFT))
        x_alignment = 0.0;
    else if (HasFlag(wxBU_RIGHT))
        x_alignment = 1.0;

    float y_alignment = 0.5;
    if (HasFlag(wxBU_TOP))
        y_alignment = 0.0;
    else if (HasFlag(wxBU_BOTTOM))
        y_alignment = 1.0;
    
    gtk_button_set_alignment(GTK_BUTTON(m_widget), x_alignment,
y_alignment);

// existing code

    ApplyWidgetStyle( false );
}

Second try:

// existing code

    gtk_button_set_label(GTK_BUTTON(m_widget), wxGTK_CONV(labelGTK));
    gtk_button_set_use_stock(GTK_BUTTON(m_widget), FALSE);

    ApplyWidgetStyle( false );

// added code
    
    float x_alignment = 0.5;
    if (HasFlag(wxBU_LEFT))
        x_alignment = 0.0;
    else if (HasFlag(wxBU_RIGHT))
        x_alignment = 1.0;

    float y_alignment = 0.5;
    if (HasFlag(wxBU_TOP))
        y_alignment = 0.0;
    else if (HasFlag(wxBU_BOTTOM))
        y_alignment = 1.0;
    
    gtk_button_set_alignment(GTK_BUTTON(m_widget), x_alignment,
y_alignment);
}

Third try:

// existing code

    gtk_button_set_label(GTK_BUTTON(m_widget), wxGTK_CONV(labelGTK));  
    gtk_button_set_use_stock(GTK_BUTTON(m_widget), FALSE);

// added code

    gtk_button_set_alignment(GTK_BUTTON(m_widget), 0.5, 0.5);

// existing code

    ApplyWidgetStyle( false );
}
