Hello, I need to change the font of a label with a condition but it seems there is a bug or I am doing it wrong, for example: from java.awt import Font nom = event.source.parent.getComponent('ioParamNom') nom.font = Font('MV boli', Font.ITALIC, 30) the inital text font is ('Dialog', Font.BOLD, 10) The font works and the style works but not the size So I tried changing the Font and the style, always works but it doesn't take the size I tried testing with button, when I click the button, it runs the code above and I see that the size changes to 30 for a second but comes back to inital 10 ---

> [@David\_Gonzalez](#): > > it runs the code above and I see that the size changes to 30 for a second but comes back to inital 10 I am unable to replicate this behavior. I change the font of a label using your script, and it works perfectly. I even closed the designer and reopened it. It remembered. What version of ignition are you using? Presently, I'm testing on 8.1.20 ---

I'm on V8.1.18 It's weird because when I run it in the designer pressing the button play, it works It doesn't work when I launch it from "Tools-\>Launch Project-\>Launch (windowed)" ---

Yup; you are correct. When I run it outside of the designer in an actual session, there is no noticeable change in size. I wonder if this is because the font automatically changes size proportionally to the label, and in the actual session, the label itself holds its dimensions. ---

I set up an experiment where I forcibly changed the label's size [using this](https://docs.inductiveautomation.com/display/DOC81/system.gui.transform): ```auto system.gui.transform(nom, nom.x, nom.y, 200, 200) ``` It did change the size of the label, but if the vertical alignment is not set to "Top," the label appears to move when the width and height change ---

Injecting HTML into the label changed the font size as expected in the actual session: ```auto from java.awt import Font nom = event.source.parent.getComponent('ioParamNom') nom.font = Font('MV boli', Font.ITALIC, 30) labelText = "TestText" nom.text = "

" + labelText + "

" ``` ---

Yes! Thanks It worked on a label even with this short code: ```auto nom.text = "" + labelText ``` BUT, I tried with a "Text Field" and a "Text Area", it doesn't work ---

> [@David\_Gonzalez](#): > > "Text Field" and a "Text Area", I'm able to replicate this. The font size doesn't change. If I highlight the text, it changes for a second, and then snaps back to the smaller size. It works as expected in the designer though. ---

I even set up a style customizer tied to a custom property I called fontSize. When I changed the custom property, it was the same result. The style was applied for a moment, and then, it was immediately overwritten. Again, the approach worked as expected in the designer, but not in an actual session. ---

Will probably have to use Java (Perhaps the UIManager) in order to get this to work. > **[Synthetica - Java Look And Feel](https://www.jyloo.com/synthetica/customize/#General)** > > Jyloo Software is a leading Java Look and Feel and Swing component provider. Based on Java Swing technology, Jyloo, JAVASOFT software products are user friendly, come along with a modern look, provide consistency and a high grade of customizability. Maybe the `Synthetica.font.scaleFactor`? There are some limitations to what Swing is capable of though. ---

Did y'all turn off 'Scale Font' in the layout settings? [https://docs.inductiveautomation.com/display/DOC81/Working+with+Vision+Components#WorkingwithVisionComponents-RelativeLayout](https://docs.inductiveautomation.com/display/DOC81/Working+with+Vision+Components#WorkingwithVisionComponents-RelativeLayout) Note that even if the component is _anchored_, the 'Scale Font' checkbox still applies. ---

> [@paul-griffith](#): > > l turn off 'Scale Font' in the layout settings That needs to be marked as the solution. It fixed the problem in my test environment on all components. ---

Yes thanks! It worked for me too
