GTK+ Forums

the following is apated from a popup/dialog without a close button. it is from a simple text editor that i thought would teach me something about creating "Close" buttons on short menu dialogs. i've done what you guys suggested above to no avail.


#include <gtk/gtk.h>

/* remove text window when button is pressed */
static gint
remove_text_window (GtkWidget *widget, GdkEventExpose *event, GtkWidget * text_window)
{
gtk_widget_destroy (text_window);
return FALSE;
}


int
main( int argc, char *argv[])
{

GtkWidget *window;
GtkWidget *close;
GtkWidget *vbox;
GtkWidget *hbox;
GtkWidget *halign;
GtkWidget *valign;
GtkWidget *label;
gtk_init(&argc, &argv);

window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
gtk_window_set_default_size(GTK_WINDOW(window), 350, 200);
gtk_window_set_title(GTK_WINDOW(window), "GtkAlignment");
gtk_container_set_border_width(GTK_CONTAINER(window), 10);



/* only string in Help/show ...*/
label = gtk_label_new ("Text Editor\nGtk / C\nVersion 4.5\n\nCopyRight\nAll Rights Reserved\n");
gtk_container_add (GTK_CONTAINER (window), label);

vbox = gtk_vbox_new(FALSE, 5);
valign = gtk_alignment_new(0, 1, 0, 0);
gtk_container_add(GTK_CONTAINER(vbox), valign);
gtk_container_add(GTK_CONTAINER(window), vbox);

hbox = gtk_hbox_new(TRUE, 3);

close = gtk_button_new_with_label("Close");
gtk_container_add(GTK_CONTAINER(hbox), close);

halign = gtk_alignment_new(1, 0, 0, 0);
gtk_container_add(GTK_CONTAINER(halign), hbox);

gtk_box_pack_start(GTK_BOX(vbox), halign, FALSE, FALSE, 0);

gtk_signal_connect (GTK_OBJECT (close), "button_press_event",
(GtkSignalFunc) remove_text_window, window);

gtk_widget_show_all(window);

gtk_main();

return 0;
}

i figured i can cobble together a few function that takes "tht" and outputs "that" and around 133 other common abbreviations and add to this editor. vim or gvim is a bit complex for new users. at any rate, i figured i would *at least* be able to add a close button to my help dialogs. i ran into the same problems i had before and trying to fix them so far has has no success. if there are quick fixes for this problem, i would be much obliged for some help...!

Hi.

I updated your code a bit, since it was using some long-deprecated stuff (gtk_signal_connect() for example). I hope this code does what you want. If you need some more explanation, just ask.

as often happens, about 20 minutes after i posted my try, i did get what your post gives. A blank window with a [Close] button in the lower right. but in my revision and is whast you posted, i see no Text and no Copyright strings. i am using gtk 2.24 [i think] on ubuntu 11.10.

maybe i am missing some library?

in my Help menu, i have three drop-down items that should be more or less stable: authors+everyone who helped me create VBC, instructions on using the program, and maybe a brief "About" dialog. in short, i'm looking for something the naive user can click on and read, with a Close button in the lower right.

what i finally came up with, and your code only gives me an empty dialog window with the Close button.

how-to fix?

Hi Gary,

I have tried out Tadej's example on my machine and it works OK (Debian using GTK+ 2.24). Ubuntu seams to be playing around a lot with themes, fonts etc. So first check that your font and theme settings are OK and that colours are set OK for example you do not have white text on a white background. Also when you run the example via a "xterm" console do you get any warnings posted.

Also note there is a widget just for doing an about dialog it is called GtkAboutDialog. You can use it to display in a standardised way a short description of your application and all the credits as wells as links for web sites and email. See http://developer.gnome.org/gtk/stable/GtkAboutDialog.html for more information on it.

Errol (and Tadej),

AAAARRRRGH! yes. i hadn't copy/pasted the correctly and it never compiled.[1] *worse*, because i have 6 or 7 examples in my directory, i wasn't sure. [[yes, i used grep in my "checking", but missed it nevertheless. i'm sorry for this mess-up.]]

[1]:: i mean, it did compile, but i didn't see the error messages until a few minutes ago.
