hello all,
I need centered text (horizontal and vertical) in gtktextview, i wrote some code, but I think it's too complicated and it work only with one line of text, (becouse next lines have too much big distance, becouse I use gtk_text_view_set_pixels_above_lines to make text vertical centered).
here is main part of code :
Code:
GtkTextBuffer *buff=gtk_text_view_get_buffer(GTK_TEXT_VIEW(view));
GtkTextIter iter;
gtk_text_buffer_get_start_iter(buff,&iter);
gtk_text_buffer_insert(buff,&iter,"text",-1);
gtk_text_view_set_justification(GTK_TEXT_VIEW(view),GTK_JUSTIFY_CENTER);/*horizontal justification is simple*/
GdkRectangle visible_rect;
gtk_text_view_get_visible_rect(GTK_TEXT_VIEW(view),&visible_rect);/*get size of gtk_text_view, we need height*/
gtk_text_view_set_pixels_above_lines(GTK_TEXT_VIEW(view),visible_rect.height/2);/*set distance between lines, which provide vertical justification, but only for one line*/
And here is full source code :
Code:
#include <gtk/gtk.h>
static void ondestroy( GtkWidget *widget, gpointer data )
{
gtk_main_quit();
}
int main( int argc, char *argv[] )
{
GtkWidget *view;
GtkWidget *window;
gtk_init(&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_default_size(GTK_WINDOW(window), 400, 300);
g_signal_connect(G_OBJECT(window), "destroy", G_CALLBACK(ondestroy), NULL);
gtk_container_set_border_width(GTK_CONTAINER(window), 16);
view = gtk_text_view_new();
gtk_container_add(GTK_CONTAINER(window),view);
gtk_widget_show(view);
gtk_widget_show(window);
GtkTextBuffer *buff=gtk_text_view_get_buffer(GTK_TEXT_VIEW(view));
GtkTextIter iter;
gtk_text_buffer_get_start_iter(buff,&iter);
gtk_text_buffer_insert(buff,&iter,"text",-1);
gtk_text_view_set_justification(GTK_TEXT_VIEW(view),GTK_JUSTIFY_CENTER);
GdkRectangle visible_rect;
gtk_text_view_get_visible_rect(GTK_TEXT_VIEW(view),&visible_rect);
gtk_text_view_set_pixels_above_lines(GTK_TEXT_VIEW(view),visible_rect.height/2);
gtk_main();
return 0;
}
Thanks for any solutions
