how to create a window in gimp plugin?

permalink

Hello,everybody!

I want to create a window in gimp plugin,so this is my code(part of the
plugin):

/static void run (const gchar *name,
gint nparams,
const GimpParam *param,
gint *nreturn_vals,
GimpParam **return_vals)
{
static GimpParam values[1];
GimpPDBStatusType status = GIMP_PDB_SUCCESS;
GimpRunMode run_mode;
GtkWidget *window;

gtk_init();

/* Setting mandatory output values */
*nreturn_vals = 1;
*return_vals = values;

values[0].type = GIMP_PDB_STATUS;
values[0].data.d_status = status;

/* Getting run_mode - we won't display a dialog if
* we are in NONINTERACTIVE mode */
run_mode = param[0].data.d_int32;

window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_title(GTK_WINDOW(window),"hello");
gtk_widget_show(window);

gtk_main();

}

/but when I ran the plugin in gimp,it didn't work...
and this is the error message:

I'm not sure if this helps, but when I've created gimp plugins, I've
always used gimp_dialog_new () instead of gtk_window_new ().

For an example, take a look at the scale_dialog () method here:

One way that always works is looking at how other plug-ins does it, for
example:
http://git.gnome.org/cgit/gimp/tree/plug-ins/common/decompose.c

Look in/around decompose_dialog()

Please have a look at
http://developer.gimp.org/writing-a-plug-in/1/index.html

In particular part III of this tutorial should be helpful.

Hi,
thanks for your tutorials,plugin examples and suggestions.

now it's fixed,if I use gimp_ui_init instead of gtk_init,I can create a
GtkWindow in gimp plugin now.

thank you all! :-)

Todong Ma
