![]() I have this idea of storing all the values in a Collection (instead of all those single variables) // Set Palette Color Values for Light ThemeĪnd use LookUp in the Themes.json "palette": [ ![]() avoid having to declare any variable in the OnStart event of the application.make sure that (just like in your proposed solution) when inserting a new control from the PowerApps Insert tab, it relies on the THEME CONTROLS and THEME PALETTE.change the properties of the lower CONTROLS section controls, thus impacting all controls used in the application.change the palette by altering the elements in the upper PALETTE section of the screen, thus impacting the lower CONTROLS section controls, then impacting all controls used in the actual application screens.Putting all this together would allow us to: Then in the JSON file we would set the values of the palette to point to the colors and values in the PALETTE section of the screen, like this:Īnd the controls styles properties values would point to the controls properties in the CONTROLS section of the screen, like this (all controls properties would have to be added in the JSON file): You can see an example on the capture above: the button's Fill property would be set to point to the Primar圜olor1.Fill property of the rectangle in the PALETTE section. In the lower CONTROLS section we could insert every possible PowerApps controls which properties would be pointing at the palette above. In the upper PALETTE section we would use rectangles'fill property to define palette color values, text inputs for numbers, etc. In this reflexion I ended up imaginating that we could design a Theme screen as this: Also, the goal would be to try to get rid of the list of variables declared in the OnStart part of the application. So I must admit your idea of putting variables directly inside the JSON theme file instead of just RGBA values is just brilliant (I am so disappointed at myself for not thinking about it earlier ).īut now I am trying to see how I could mix the idea of using variables in the theme file with a more sophisticated interface to edit the palette values and change the default controls properties directly in the target application (thus replacing your Theme palette screen with a screen like the one I was building in my PowerApps CTG app). Its imperfections lies in the fact that it produces a JSON file that you must then manually reinject in you package file and that any existing control within the targeted app (when the theme JSON file is repackaged) would not automatically use the new template but only newly added controls. a version where you can set the default colours, width, height etc at a control-level (for Insert> items) so you could specify buttons as one set of colours for all new items and labels as another set of colours and sizes etc been working for quite a time now on an application called PowerApps CTG (Custom Theme Generator) that would be similar to the PowerApps Theme Editor by that would be made WITH PowerApps so one could see the result right away on the various PowerApps controls.a stripped-down version where you only need to set three colours and three text colours (to match those colours).msapp file was my attempt at making it as user-friendly as possible while still allowing customization throughoutįuture versions I plan on releasing will be: so creating this by reconstructing the actual. Yes, I originally had a copy-paste screen with controls and anyone could easily make something similar using this by creating a default copypaste screen with the Insert controls and then defining the shape or size to your needs - my main gripe with the copypasta method is/was that its not intuitive and your users will generally keep trying to use the Insert> method and will then set the colours manually which you then need to clean up or fix later if you are using theming Thanks for your comment Really appreciate it json files inside, extract it to a folder, do your editing, and then run the following powershell script (within this repository) from within that extracted folder after you've done modifications, which will reconstitute it into a.
