Hello,
I'm imagining simply a label with a background color (usually Grey) and a
foreground color (the color of the writing usually black). But I want to
change this! I've managed to change the foreground color to white but didn't
manage to change the background to green using GtkStyle under Gtk-1.2.
Any help would be greatly appreciate :-)
Here is the code I'm using :
void
on_smnuAbout_activate (GtkMenuItem *menuitem,
ast_pointer user_data)
{
GtkWidget *wndAbout = NULL;
GtkWidget *ABOUT_lblNameVersion = NULL;
GdkColor CouleurTitreFond;
GdkColor CouleurTitrePolice;
GdkColormap *ColorMap = NULL;
GtkStyle *gtkTitleStyle = NULL;
/* Creation of the About window (Glade generated function) */
wndAbout = create_wndAbout();
ABOUT_lblNameVersion = lookup_widget(wndAbout, "ABOUT_lblNameVersion");
/* Retrieve the colormap of the widget to alloc new color to it */
ColorMap = gtk_widget_get_colormap(ABOUT_lblNameVersion);
/* Make a green color */
CouleurTitreFond.red = 29184;
CouleurTitreFond.green = 41984;
CouleurTitreFond.blue = 33536;
gdk_colormap_alloc_color(ColorMap, &CouleurTitreFond, FALSE, TRUE);
gdk_color_parse("white", &CouleurTitrePolice);
gdk_colormap_alloc_color(ColorMap, &CouleurTitrePolice, FALSE, TRUE);
/* I don't know if this is needed, but in case... */
gtk_widget_set_colormap(ABOUT_lblNameVersion, ColorMap);
gtkTitleStyle = gtk_style_copy(ABOUT_lblNameVersion->style);
gtkTitleStyle->bg[GTK_STATE_NORMAL] = CouleurTitreFond;
gtkTitleStyle->bg[GTK_STATE_ACTIVE] = CouleurTitreFond;
gtkTitleStyle->bg[GTK_STATE_PRELIGHT] = CouleurTitreFond;
gtkTitleStyle->bg[GTK_STATE_SELECTED] = CouleurTitreFond;
gtkTitleStyle->bg[GTK_STATE_INSENSITIVE] = CouleurTitreFond;
gtkTitleStyle->fg[GTK_STATE_NORMAL] = CouleurTitrePolice;
gtkTitleStyle->fg[GTK_STATE_ACTIVE] = CouleurTitrePolice;
gtkTitleStyle->fg[GTK_STATE_PRELIGHT] = CouleurTitrePolice;
gtkTitleStyle->fg[GTK_STATE_SELECTED] = CouleurTitrePolice;
gtkTitleStyle->fg[GTK_STATE_INSENSITIVE] = CouleurTitrePolice;
gtk_widget_set_style(ABOUT_lblNameVersion, gtkTitleStyle);
gtk_style_unref(gtkTitleStyle);
gtk_widget_show_all(wndAbout);
}
