This time we will create a graphic user interface to make a pdf with Python. Go here<\/a> to see the code to make it without the GUI.<\/p>\n

Now, we will divide the code in 2. One to create the pdf and another to create the GUI. Launching the first, you can still make the pdf, but you need to change the text in the code itself, in the text variable. Launching the GUI, you can change the text into a Text widget called content. Having a file for the logic and a file for the GUI, makes it easy to change both of them, separately.<\/p>\n

The script (working also alone) to make the pdf<\/h2>\n

If you do not want to use a GUI, you can use the one above. Works perfectly alone. If you prefer a GUI, go to the next chapter and use both the script in the same folder, calling the one above pdfcreate2.py<\/p>\n
The GUI to make the pdf importing pdfcreate2<\/h2>\n
This is the very simple GUI. You have a template at the beginning, but you can change it as you want.<\/p>\n
