So I’m trying to set the font of a label when the screen the label on is shown. I have gone around into a few places but it doesn’t seem to work. I currently have this script running on the container that holds the label. ```auto from java.awt import Font if event.propertyName == "componentRunning" and event.newValue: print event.source.getComponent('bannerText').font event.source.getComponent('bannerText').font = Font('Arial', Font.BOLD, 50) print event.source.getComponent('bannerText').font ``` The print statements appear to act correctly… ```auto java.awt.Font[family=Arial,name=Arial,style=bold,size=20] java.awt.Font[family=Arial,name=Arial,style=bold,size=50] ``` ---

Why not just set the font property? ---

This is a simplified example. We are going to be passing each label into a script to initialize it so they all look the same. Also that way if we need to change it, we can change it in 1 location for every label without having to go to each screen. We are doing the same thing with tables. Each table gets passed to a script that sets up all the aspects so they are all the same. ---

In the a project startup script, create a font entry in globals: ```auto from java.awt import Font globalFont = Font('Arial', Font.BOLD, 50) system.util.getGlobals()['globalFont'] = globalFont ``` In the propertyChange script for the label: ```python # The 'text' property fires every time a screen starts if event.propertyName == 'text': # Get component object and global font component = event.source globalFont = system.util.getGlobals()['globalFont'] # set component to global font, if they don't match if component.font != globalFont: component.font = globalFont ``` After you get the desired effects you want, you can put this label into a custom component pallete and use it wherever you wish. ---

That doesn’t work either. I can see from the print statements that the font is taking, but the screen doesn’t update. It’s like you need to invoke a repaint of the screen. ---

What version are you using? I tested this under 8.0.9. 😕 ---

Are you testing in the designer only? What about a ‘real’ client? I strongly suspect something else is at play here. ---

I had tested it from the stand alone client launcher and from the client launched from the designer and by putting the designer into preview mode. None of them were working. We just so happen to have to reboot the dev system today and it now works in all 3 cases. And just like that the problem is back. Now it will only work when i put the designer into Preview mode. Launching the client in any way causes it not to work. This is now on the label component ```auto if event.propertyName == 'text': print event.source.font print theme.label.pageTitle() event.source.font = theme.label.pageTitle() print event.source.font ``` Here is the script “theme.label.pageTitle()” ```auto from java.awt import Font def pageTitle(): return Font('Arial', Font.BOLD, 50) ``` Here is the console output ```auto java.awt.Font[family=Arial,name=Arial,style=bold,size=23] java.awt.Font[family=Arial,name=Arial,style=bold,size=50] java.awt.Font[family=Arial,name=Arial,style=bold,size=50] ``` This is the complete console when launched from Client Launcher ```auto 19:41:01.248 [Thread-0] INFO com.inductiveautomation.ignition.client.gateway_interface.GatewayConnectionManager - Updated login state.

You’ve tried this script on a brand new window, no bindings, other scripts, etc? What if you use ‘Dialog’ instead of ‘Arial’? What if you change the script where you’re assigning; use: ```auto newFont = theme.label.pageTitle() print newFont event.source.setFont(newFont) ``` ---

I tried it using the setFont method and that appears to make it work 100% of the time now. Is there an issue when just setting it equal to a font as I was doing verse using the setFont method? I would have thought they would produce the exact same result. ---

They _should_, but it is a little bit of Jython “magic”; Java code style discourages publicly accessible properties, and instead encourages the ‘Bean’ pattern, where there’s a private field and a `getX()`/`setX()` method. Jython does some under-the-hood stuff to turn `getX/setX` into an accessible “property” `x` - so your code, assigning `component.font = something` is _technically_ calling `component.setFont(something)`; or at least, it should be. It’s not inconceivable that this breaks down somewhere; either because of something about Ignition’s components, or the way we call Jython code, etc. ---

Simple enough. Thanks for the explanation. I figured since the property was exposed that I should use that instead of the get/set idea that I’m used to in Java. If I encounter weird bugs, I’ll know to try the getter and setter first and go from there.
