Explanation
- When you create a table with
new GtkTable, it is not necessary to define the number of rows and columns. Tables are dynamic in PHP-GTK2, i.e. you can add any number of columns and rows on the fly in your program.
- Too lazy to write a whole bunch of
GtkTable::attach statements. So wrote a small function for this.
- Align the label to the left. You may want to refer to How to left or right align GtkLabel in GtkWindow for more information about label alignment.
- Put the contents in the respective cell with GtkTable::attach().
Note the use of Gtk::FILL, Gtk::SHRINK. Try it. If you don't specify these two values, the two labels will be spaced out apart (both in the x and y directions), as shown below:
Note
Note that the table is aligned to the left. If you wish to have the table centered (as shown below), pleae refer to Part 2
