| + | == Tips & Tricks == |
| + | |
| + | In order to insert some special template like MathBoxes, vectors shapes, angles etc., you have to put these in the '''setExpression''' argument : |
| + | *\\1angle : The text rendered inside is will be displayed under the "angle" shape |
| + | *\\1circle : Symbol for circle |
| + | *\\1keyword : |
| + | *\\1line : Symbol for line (parenthesis) |
| + | *\\1lineseg : Symbol for line segment |
| + | *\\1ray : |
| + | *\\1rtri : |
| + | *\\1subhead : |
| + | *\\1subscrp : Subscript text |
| + | *\\1supersc : Superscript text |
| + | *\\1title : |
| + | *\\1tri : Triangle symbol |
| + | *\\1vector : The text rendered inside is will be displayed under the vector arrow. |
| + | *\\1word : |
| + | *\\0el {''content''} : Inserts a MathBox with the ''content'' inside it. |
| + | |
| + | For example, '''editor:setExpression("\\1vector AB")''' will render as : http://i.imgur.com/aqVd8.jpg |
