C Language Learning (2)-GTK layout, C Language Learning-gtk Layout
First, understand the Definition Format of the function in gtk:

Remember the following formats.

Declare variable: GtkAbc * abc = gtk_abc_new () Declare control; Value assignment: gtk_abc_set_label (controlName, value ); Add to parent container: gtk_container_add (controFather, controlChildl ); Display Control: gtk_widget_show (controlName ); General default value: the last three values of gtk_box_pack_start (), which are generally FALSE, FALSE, and 0.

1. Box layout (vertical and horizontal)

 

# Include <stdio. h> # include <gtk/gtk. h> int main (int argc, char * argv []) {// initialize gtk gtk_init (NULL, NULL ); // define a pointer to the window: GtkWindow * window = gtk_window_new (GTK_WINDOW_TOPLEVEL); // After the form is closed, execute g_signal_connect (window, "destroy", gtk_main_quit, NULL ); // set the title gtk_window_set_title (window, "title"); // each added control must have show gtk_widget_show (window); // Add a box, use vertical layout // GTK_ORIENTATION_HORIZONTAL for horizontal layout GtkBox * box = gtk_box_new (GTK_ORIENTATION_VERTICAL, 0); gtk_container_add (window, box); gtk_widget_show (box ); gtkLabel * lb1 = gtk_label_new ("box layout"); gtk_container_add (box, lb1); gtk_box_pack_start (box, lb1, FALSE, FALSE, 0); gtk_widget_show (lb1 ); gtkEntry * entry1 = gtk_entry_new (); gtk_container_add (box, entry1); gtk_box_pack_start (box, entry1, FALSE, FALSE, 0); gtk_widget_show (entry1 ); gtkButton * btn1 = gtk_button_new (); gtk_button_set_label (btn1, ""); gtk_container_add (box, btn1); gtk_box_pack_start (box, btn1, FALSE, FALSE, 0 ); gtk_widget_show (btn1); gtk_main (); return 0 ;}

The running result is as follows:

Gtk_grid_attach (grid1, btn1, 1, 2, 3, 4 ):
Grid1 indicates the parent container;
Btn1 indicates the added control;
1 indicates that the control is a grid on the left;
2 indicates that the control is two grids above it;
3 indicates that the control occupies the width of three grids;
4 indicates that the control occupies the height of four grids;

Remember a few words:

1. the keyword of Grid layout is Grid. 2. gtk_button_set_label () indicates the value assignment, and set_label () is used for the value assignment () 3. gtk_container_add () should be written after gtk_grid_attach ()

# Include <stdio. h> # include <gtk/gtk. h> int main (int argc, char * argv []) {gtk_init (NULL, NULL); GtkWindow * window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_window_set_title (window, "grid layout"); g_signal_connect (window, "destroy", gtk_main_quit, NULL); gtk_widget_show (window); GtkGrid * grid1 = gtk_grid_new (); gtk_container_add (window, grid1 ); gtk_widget_show (grid1); GtkButton * btn1 = gtk_button_new (); break (btn1, "111111"); gtk_grid_attach (grid1, btn1,); gtk_container_add (grid1, btn1 ); gtk_widget_show (btn1); GtkButton * btn2 = gtk_button_new (); Second (btn2, "222222"); gtk_grid_attach (grid1, btn2,); Second (grid1, btn2 ); gtk_widget_show (btn2); gtk_main (); return 0 ;}

The running result is as follows:

Today, I have written so much. I don't have a high goal. I hope to write an article every day. I want to learn more about the details and then I will try to add it.
