DocumentHandler | phonegap plugin to handle documents | Document Editor library

The documentation of QTextDocument::setDefaultStyleSheet says:

Note: Changing the default style sheet does not have any effect to the existing content of the document.

You try to overcome this by calling setHtml after setDefaultStyleSheet like that:

First, when the compiler encounters an overloaded method of constructor, it needs to be able to resolve which overload this is based on information that it has about types from earlier. In your case, there is no type hint that would help it, so it fails. You can fix that by adding a type annotation, e.g. on the lambda function:

So I solved it by just selecting everything and deselecting when the text changes. Theoretically I only need to do it when I am in a Table Block.

In general, you don't -- you don't change the state of the Document while listening to it when using a DocumentListener. The two possible solutions that I know of:

• From within your Listener, put the code that makes the changes that you wish to make within a Runnable and queue the Runnable onto the Swing event thread by calling SwingUtilities.invokeLater(yourRunnable). This is a shameless kludge
• Much better: Don't use a DocumentListener but rather a DocumentFilter since this type of listener was geared towards making changes to the Document before the text is visualized within the component.

Unrelated side issue: your code shows a worrisome degree of coupling in that you try to change the text in a specific text component from within your listener. DocumentListeners should be fully agnostic of the text component whose document that they listen to, and in fact may be added to more than one Document.

A DocumentFilter has 3 methods that need to be overridden and do what you expect them to do: what you would expect them to do:

• insertString: insert a String into the document
• remove: removes text from the document
• replace: replaces text in the document

What is more, these methods do their actions before the text component renders the changes to the document.

So within my method overrides, I extract the current document's text, and use the parameters to create what the new text will look like, for example for the replace method I did:
