Hello,
I wonder is there any easy way to make JUCE::Label editable partly? Or do I need to write my own method or class?
I mean something like that, my label text is for example “x / 10”, and I want to be able to edit only “x”.
I think you would have to make your own custom implementation for this, I’m not sure of any JUCE features that allow for this…
I believe one way you could do it is to have some sort of “post-fix” text that is always added to the “editable” text.
Then whenever the label shows its editor - Label::editorShown() - you can set the editor’s text to just the editable part (“x”), and when it’s hiding - Label::editorAboutToBeHidden() - you can add the post-fix text (" / 10") to what the user typed in (the new text for “x”).
At least that’s one way I’ve handled this kind of thing before 
if you want it to be where just the text editor appears over the “x” then you could achieve it by using two labels and some positioning…
