Widget problem [GTK RELATED]

[darekg11]

Hi, I decided to make new structure of GtkWidget's and also a function which will organise them in my order, it looks like:

Structures:

typedef struct{
	std::string tytul,opis,typ;
	short int godzina,minuta,p_godzina,p_minuta,dzien,miesiac,rok,ID,ilosc;
} Wydarzenie;

typedef struct{
	std::string kawalek_opisu;
	short int ID;
	GtkWidget* Labels[5];
	GtkWidget* Vbox;
	GtkWidget* Hboxs[2];
	GtkWidget* Event_Box;
} NowyWidget;

Function to create "new" widget:

NowyWidget nowy_widget_init(Wydarzenie wydarzenie)
{
	std::string czas;
	char bufor[3] = {0};
	NowyWidget widget;
	widget.Event_Box = gtk_event_box_new();
	gtk_widget_set_events (widget.Event_Box, GDK_BUTTON_PRESS_MASK);
	for (int i = 0; i < 2; ++i) widget.Hboxs[i] = gtk_hbox_new(FALSE,0);
	widget.ID = wydarzenie.ID;
	widget.kawalek_opisu.assign(wydarzenie.opis,0,20);
	widget.kawalek_opisu += "...";
	widget.Labels[0] = gtk_label_new(wydarzenie.tytul.c_str()); // Labels[0] tytul;
	widget.Labels[1] = gtk_label_new(wydarzenie.typ.c_str()); //Labels [1] typ;
	widget.Labels[2] = gtk_label_new(widget.kawalek_opisu.c_str());

	itoa(wydarzenie.p_godzina,bufor,10);
	czas = bufor;
	czas += ":";
	itoa(wydarzenie.p_minuta,bufor,10);
	czas += bufor;

	widget.Labels[3] = gtk_label_new(czas.c_str());

	czas.clear();

	itoa(wydarzenie.godzina,bufor,10);
	czas = bufor;
	czas += ":";
	itoa(wydarzenie.minuta,bufor,10);
	czas += bufor;

	widget.Labels[4] = gtk_label_new(czas.c_str());
	widget.ID = wydarzenie.ID;
	widget.Vbox = gtk_vbox_new(FALSE,0);
	gtk_container_add(GTK_CONTAINER(widget.Event_Box),widget.Vbox);
	gtk_box_pack_start(GTK_BOX(widget.Vbox),widget.Hboxs[0],FALSE,FALSE,0);
	gtk_box_pack_start(GTK_BOX(widget.Hboxs[0]),widget.Labels[0],FALSE,FALSE,0);
	gtk_box_pack_end(GTK_BOX(widget.Hboxs[0]),widget.Labels[1],FALSE,FALSE,0);
	gtk_box_pack_start(GTK_BOX(widget.Vbox),widget.Hboxs[1],FALSE,FALSE,0);
	gtk_box_pack_start(GTK_BOX(widget.Hboxs[1]),widget.Labels[2],FALSE,FALSE,0);
	gtk_box_pack_start(GTK_BOX(widget.Hboxs[1]),widget.Labels[3],FALSE,FALSE,0);
	gtk_box_pack_end(GTK_BOX(widget.Hboxs[1]),widget.Labels[4],FALSE,FALSE,0);
	return widget;
}

I also made a vector of this "new" widgets and use it like that in code:

std::vector<NowyWidget> zbior_widgetow;

Wydarzenie temp;
	NowyWidget duzo;
	temp.dzien = 1;
	temp.godzina  = 1;
	temp.ID = 1;
	temp.ilosc  = 1;
	temp.miesiac = 1;
	temp.minuta = 1;
	temp.opis = "test";
	temp.p_godzina = 1;
	temp.p_minuta = 1;
	temp.rok = 1;
	temp.typ = "TEST";
	temp.tytul = "TESTING";
	for (int i = 0; i < 10; ++i) 
	{
		memset((void*)&duzo,0,sizeof(NowyWidget));
		duzo = nowy_widget_init(temp);
		zbior_widgetow.push_back(duzo);
	}

for (unsigned i = 0; i < zbior_widgetow.size(); ++i) gtk_scrolled_window_add_with_viewport(GTK_SCROLLED_WINDOW(Okno_przesuw),zbior_widgetow[i].Event_Box);

And GTK allows me to place only one widget, with the rest I get:

"gtk_scrolled_window_add_with_viewport : assertion 'GTK_BIN (bin->child)->child == NULL' FAILED, and it palces only the first one widget in window.

Any help needed

Mods... this should be moved to C++

[darekg11]

It's bassicly C , just using std::vector whole GTK is in C so I tihnk it fits here more.

Ok... but you're far more likely to get good answers in the other forum.

How about we let the moderators decide...

[darekg11]

I think i can get anwsers of better quality here because whole GTK interface is in C and problem probably occours because of some bad deleting widgets or something like that and not even touches vector. Anyway moderators will decide.

EDIT: I'm such a retard I had to put Vbox first in scrolled window.... Moderators please close/delete topic.

Moderators please close/delete topic.

Why should they? It is a legit case that may be helpful to others.
