Hi guys,
I tried to show or hide some gtk_widget depending on a certain condtion.
I put in a callback function things like:
sichtbar[k][i] ? gtk_widget_show((GtkWidget *)lbl_frequenz) :
gtk_widget_hide((GtkWidget *)lbl_frequenz); i++;
sichtbar[k][i] ? gtk_widget_show((GtkWidget *)lbl_amplitude) :
gtk_widget_hide((GtkWidget *)lbl_amplitude); i++;
sichtbar[k][i] ? gtk_widget_show((GtkWidget *)lbl_offset) :
gtk_widget_hide((GtkWidget *)lbl_offset); i++;
sichtbar[k][i] ? gtk_widget_show((GtkWidget *)lbl_einzeit) :
gtk_widget_hide((GtkWidget *)lbl_einzeit); i++;
sichtbar[k][i] ? gtk_widget_show((GtkWidget *)lbl_risetime) :
gtk_widget_hide((GtkWidget *)lbl_risetime); i++;
sichtbar[k][i] ? gtk_widget_show((GtkWidget *)lbl_falltime) :
gtk_widget_hide((GtkWidget *)lbl_falltime); i++;
sichtbar[k][i] ? gtk_widget_show((GtkWidget *)lbl_triggermodus) :
gtk_widget_hide((GtkWidget *)lbl_triggermodus); i++;
sichtbar[k][i] ? gtk_widget_show((GtkWidget *)lbl_polaritaet) :
gtk_widget_hide((GtkWidget *)lbl_polaritaet); i++;
sichtbar[k][i] ? gtk_widget_show((GtkWidget *)lbl_triggerampli) :
gtk_widget_hide((GtkWidget *)lbl_triggerampli); i++;
sichtbar[k][i] ? gtk_widget_show((GtkWidget *)lbl_triggerdelay) :
gtk_widget_hide((GtkWidget *)lbl_triggerdelay); i++;
sichtbar[k][i] ? gtk_widget_show((GtkWidget *)lbl_patternlaenge) :
gtk_widget_hide((GtkWidget *)lbl_patternlaenge); i++;
sichtbar[k][i] ? gtk_widget_show((GtkWidget *)lbl_patternrepeat) :
gtk_widget_hide((GtkWidget *)lbl_patternrepeat); i++;
sichtbar[k][i] ? gtk_widget_show((GtkWidget *)lbl_patternzeit) :
gtk_widget_hide((GtkWidget *)lbl_patternzeit); i++;
But some of that are leading to a segmentation fault.
Version ist gtk+ 3.0. sichtbar[k][i] is an array with 0 or 1 in it.
lbl_xxx is implemented like: lbl_frequenz = GTK_LABEL
(gtk_builder_get_object (builder, "label_frequenz"));
Does anybody know what is wrong?
Cheers,
Axel
