How to build tfe (text file editor)

How to compile and execute the text editor 'tfe'.

First, source files are in the Gtk4-tutorila repository. How to download them is written at the end of the previous section.

The following is the instruction of compilation and execution.

• You need meson and ninja.
• If you have installed gtk4 from the source, you need to set environment variables to suit your installation.
• Change your current directory to src/tfe5 directory.
• Type meson setup _build for configuration.
• Type ninja -C _build for compilation. Then the application tfe is built under the _build directory.
• Type _build/tfe to execute it.

Then the window appears. There are four buttons, New, Open, Save and Close.

• Click on Open button, then a file chooser dialog appears. Choose a file in the list and click on Open button. Then the file is read and a new Notebook Page appears.
• Edit the file and click on Save button, then the text is saved to the original file.
• Click Close, then the Notebook Page disappears.
• Click Close again, then the Untitled Notebook Page disappears and at the same time the application quits.

This is a very simple editor. It is a good practice for you to add more features.
