All, I wrote a little function to change some text
attributes in a GtkTextBuffer based on the state of some
GtkToggleButtons. When I modify the “weight” attribute to
bold, it takes effect immediately. When I attempt to modify the “foreground”
attribute to red I see no effect until I press one of the other toggles (or the
same one for that matter). I can also change the “scale”
attribute no problem, but neither the foreground or background colors take
effect until I click something else. Here are the salient parts of the
code: void change_text_attribute(gint i_attr, GtkToggleButton
*i_button) { GtkWidget *top_dog =
gtk_widget_get_toplevel(GTK_WIDGET(i_button)); GtkWidget *msgText = lookup_widget(top_dog,
"msgText_entry"); GtkTextBuffer *msgBuffer =
gtk_text_view_get_buffer (GTK_TEXT_VIEW (msgText)); GtkTextIter msgStart, msgEnd; GtkTextTag *tag; gboolean l_button_pressed =
gtk_toggle_button_get_active(i_button); gtk_text_buffer_get_bounds(msgBuffer,
&msgStart, &msgEnd); switch (i_attr) { case TEXT_BOLD: if (l_button_pressed) { if
(gtk_text_tag_table_lookup(gtk_text_buffer_get_tag_table(msgBuffer),
"bold") == NULL) {
tag = gtk_text_buffer_create_tag(msgBuffer, "bold",
"weight", PANGO_WEIGHT_BOLD, NULL); }
gtk_text_buffer_apply_tag_by_name(msgBuffer, "bold", &msgStart,
&msgEnd); } else {
gtk_text_buffer_remove_tag_by_name(msgBuffer, "bold", &msgStart,
&msgEnd); } break; case TEXT_RED: if (l_button_pressed) { if
(gtk_text_tag_table_lookup(gtk_text_buffer_get_tag_table(msgBuffer),
"red") == NULL) {
tag = gtk_text_buffer_create_tag(msgBuffer, "red",
"foreground", "red", NULL); } gtk_text_buffer_apply_tag_by_name(msgBuffer,
"red", &msgStart, &msgEnd); } else {
gtk_text_buffer_remove_tag_by_name(msgBuffer, "red", &msgStart,
&msgEnd); } break; } ... Any ideas? Thanks – |
