actually i'm looking for something very similar to this thread:
How to hide the controls of HTMLEditor?
so basically i try to add a custom button to the javafx html editor but with the difference that it's implemented through FXML.
So my question is:
Is there a "work-around" to add custom buttons to the html-editor when it's implemented through FXML?
Here is some sample code which customizes the HTMLEditor and adds a custom button to it. The sample code does not use fxml but really it's very similar if fxml is used. You could define the HTMLEditor in fxml and inject it into your Controller using the standard @FXML annotation. Once you have a reference to the editor, customize it in Java code using an appropriate variation of the sample code. For the added button, just create it in Java rather than fxml and it will be simpler.
Sample solution is :
htmlEditor.setVisible(false);
Platform.runLater(new Runnable() {
@Override
public void run() {
Node[] nodes = htmlEditor.lookupAll(".tool-bar").toArray(new Node[0]);
for (Node node : nodes) {
node.setVisible(false);
node.setManaged(false);
}
htmlEditor.setVisible(true);
}
});
I have modified the @jewelsea answer for javaFX9.
I have also added some customization to move toolbars. The main idea is to get all the components by css selector, then modify or hide them. Read the class HTMLEditorSkin to get the CSS classes names, like ".html-editor-align-center" for the align button.
