# 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](https://github.com/ToshioCP/Gtk4-tutorial).
|
|
How to download them is written at the end of the [previous section](sec15.md).
|
|
|
|
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 _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 FileChooserDialog 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.
