Methods

get(key) → nullable{string}

Get the saved value of the equation editor, as a LaTeX string.

Parameters

  • key string

    the key whose value should be looked up

Source

setFocusWhenShown(value)

Whether to focus this item once it has loaded. Defaults to false, so as to not interfere with the usual focus mechanics of the Dialog class. However, because this component is a unique one, the normal focus mechanics will not work for it, so you should call this function to override them if you want this item to receive focus once it has been installed into the dialog.

Parameters

  • value boolean

    whether to focus this item once it appears

Source

setValue(value)

Set the current contents of the editor to the expression represented in the given LaTeX content.

Parameters

  • value string

    LaTeX content to be put into the MathLive editor
