At last we use () to tell our window to use mainmenu as our window's menubar. Then using the add_cascade() function we tell the first Menu object to include the filemenu variable which includes all our sub-menus with the label File. and finally the Exit will execute a builtin function quit which will close the program. The Open sub-menu will execute the openfile function, the Save as sub-menu will execute savefile function. Then we add 3 sub menus (Open, Save as, Exit) and a separator using the add_command() and add_separator() functions. Next, We define another Menu and previous menu as its parent. Here we define a new Menu with Frame as its parent. To fix this we are gonna put this at the end of our script Now if you run the tdown.py script you'll not see anything, because we have only defined the class but never called it. It tells the frame to fill the window both horizontally and vertically, and the expand keyword argument is set to 1 (signifies True) and tells our Frame to be expandable, in simple terms the Frame will be filling the window no matter if we stretch the window size, or maximize it. We set fill keyword argument to BOTH which is actually being import from tkinter library. In the init_window function we first set the title of the window as TDOWN and in the next line self.pack(fill=BOTH, expand=1), we tell your Frame to take the full space of our window. Next we declare a custom font object called self.myfont with font family of Helvetica (You can choose any font family you want) and size of 14 which will be used in our markdown input field, finally we call the init_window function where we will put the heart of our application. Now in the initialization function we take master as a argument which will serve as the parent of the frame, in the next line we initialize a Frame. Here in this codeblock, we first define a class called Window which inherits tkinter's Frame widget class. We will start by importing necessary libraries.Įnter fullscreen mode Exit fullscreen mode Now fire up your favorite editor or IDE and create a new file (eg. You can install them by running pip install tkhtmlview markdown2 or pip3 install tkhtmlview markdown2 (If you have multiple versions of Python) Other Things we will need are tkhtmlview and markdown2. Ugh, I think I'm boring you □, so let's stop talking and start building.įirst make sure you have Python 3 and Tkinter installed, if not you can download them from here /downloads (Tkinter is already packed with Python). So as usual I created my own fork and fixed some issues and kinda improved the stability and named it : tkhtmlview. You can just simply write/edit markdown but there's no easy way to display the output inside your application.īut one day, while I was roaming the streets of Internet I found Something Interesting, tk_html_widgets which can display html output! But ofcourse it did have some problems: the fonts were too small, and had no support for attaching remote photos. There's not even a default tkinter widget to display html data. Because there's no default easy way to display html output of the markdown input. So, before we start, I want to explain why people don't want to build markdown editors with tkinter. Tkinter Tutorials: Tkinter Basics, FreeCodeCamp Tkinter Course, TheNewBoston Tkinter Playlist etc. If you already are familiar with Python and Tkinter you can easily get into this guide.īut If you are just starting out with Python and/or Tkinter, you can check out these : Python Tutorials: FreeCodeCamp Python Tutorial, Python 3 Playlist by sentdex, FreeCodeCamp Python for Beginners etc. (I will explain why other don't want to build markdown editor with Tkinter) In the meantime, I always been a fan of doing things which won't be done by others. Everybody is creating a markdown editor, some of them are innovative but some of them are boring. I totally use proper debugging tools and unit tests and barely use this one I swear.Markdown Editor are one of the trending things nowadays. em Units #Ībbreviation: ems expands to: ) For example, I use a macro that will automatically calculate an em value based on a supplied parent size (and output a comment documenting the math). It really gets fancy when Typinator can do user prompts (with default values) and math based on those values. How I use Typinator (a snippet manager) to automate `em` calculations in CSS (with pixel size comments):Īlt: /gM0b9r8hq5- Zach Leatherman August 28, 2017Īnd here is a small sampling of my favorite macros: Name Here is an example of what it looks like: I use this utility a lot, probably more than a hundred times per day. I don’t remember why I switched (I think it was vaguely associated with performance) but I’m happy with Typinator now. I used to use TextExpander for text expansion/macros and use Typinator now.
