base class for nodes representing text in the syntax tree
This node is a collection of tools, necessary to draw text. It is the base for nodes, such as:
◆ JKQTMathTextTextBaseNode()
| JKQTMathTextTextBaseNode::JKQTMathTextTextBaseNode |
( |
JKQTMathText * |
parent, |
|
|
const QString & |
text |

◆ ~JKQTMathTextTextBaseNode()
| virtual JKQTMathTextTextBaseNode::~JKQTMathTextTextBaseNode |
( |
| ) |
|
|

◆ getText()
| QString JKQTMathTextTextBaseNode::getText |
( |
| ) |
const |
text-contents of the node
◆ textTransform()
| virtual QString JKQTMathTextTextBaseNode::textTransform |
( |
const QString & |
text, |
|
|
const JKQTMathTextEnvironment & |
currentEv |
|
) |
| const |
|
protectedvirtual |
◆ toHtml()
convert node to HTML and returns true on success
- Parameters
-
| [out] | html | new HTML code is APPENDED to this string |
| currentEv | JKQTMathTextEnvironment object describing the current drawing environment/settings |
| defaultEv | JKQTMathTextEnvironment object describing the default drawing environment/settings when starting to interpret a node tree |
- Returns
true on success
Reimplemented from JKQTMathTextNode.
Reimplemented in JKQTMathTextVerbatimNode.
◆ text
| QString JKQTMathTextTextBaseNode::text |
|
protected |
text-contents of the node
