Calculator 09 - Refactoring
**Clean Up Your Code & Make it Shine!**
In this video, we take a step back and focus on code cleaning. We'll revisit sections of code from a previous video and see how we can improve readability and efficiency.
By removing unnecessary comments, consolidating logic, and implementing procedures, we can transform our code from functional to fantastic!
We'll also explore renaming variables for better clarity and discuss potential error handling for future improvements.
**Join us as we learn the power of code cleaning and see how it can make your code easier to understand and maintain.**

This video builds upon the previous one, demonstrating how to move multiple buttons at runtime in Delphi FMX. Refactoring is emphasized, with renaming variables (FMoving to FMovable) and event handlers (enable/disable moving, move button) for clarity. Generalization is key. Code is modified to work with any button, not just a specific one (removing "BTNMovable"). A TButton variable is introduce...

Well explained.
Should we not extract each step in to its own procedure?
Simple and useful. Thanks
Audio can be improved. Thanks anyway.
Good
Refactoring makes sense. Great
Yes. Thank you
Very nice and easy tutorial. Thanx
Thank you so much.
Thanks!
Welcome. Stay Blessed
Does the Delphi developer have a feature market?
Do you have any idea that how to resize it on runtime
Well, the actual act of resizing is simple. We just change the (Sender as TButton).Width & (Sender as TButton).Height. The tricky part is how to start this and how to provide visual feedback. The simpler solution can be to use two TTrackbar components for sizing and show them when a resize button is clicked. The elaborated solution should involve drawing a rubber band rectangle with the mouse in real time and Resize on MouseUP.
Remove the top line ... remove the readln .. compile and run from the console.

I want to build a commercial app for android in Delphi I need some advices how can I contact you?
Yes please. You can contact me at TheQasimShahzad@Gmail.com or you can join en.delphipraxis.net/ to contact with the Delphi experts
Good tuto ❤
If you were to write the same program in Delph 1 16bit it would be even smaller.
Wonderful. Exactly. It will be very small. We had many software in the range of Kilobytes in those days. Today even Gigabyte is acceptable.😄
or Turbo Pascal
@@pawoon Yes. That's it.
Finally, something straight to the point
Thank you for your appreciation. Stay Blessed
what do i have to do if it doesnt give option of windows vcl application
Kindly guide which Delphi version do you have? and Have you changed any default settings?
11.2
@@adriaan867 It's strange. I checked in 11.2, and this option is available. I think either your installation is faulty or incomplete. You may try reinstalling or downloading it from the official website for a complete package.
