Problems with .addLeaf() #42

Closed AlgebraicFloat closed 1 year ago

AlgebraicFloat commented 1 year ago

Bug description

When trying to add fractions into the mathtextfield they end up giving a parser error after trying to edit

To Reproduce

Steps to reproduce the behavior: _mathController.addLeaf(r"\frac{1"); _mathController.addLeaf("2"); _mathController.addLeaf("}{3"); _mathController.addLeaf("4"); _mathController.addLeaf("}"); _mathController.addLeaf("");

try editing the fraction using the math keyboard.

Expected behavior

It would be great if you could add fractions into the mathfield by using addLeaf(). Maybe I'm just not looking in the right places for this functionality.

"Parser Error: Expected '}', got 'EOF' makes sense since I'm deleting the bracket, but how do I make the fraction editable in the mathtextfield?

Hi @AlgebraicFloat, please have a look at addFunction() for everything that takes arguments (e.g. like fractions do)🙂
