Vuetify allows us to change the default themes and presets by using a variables.scss/sass file in our project.
But I am unable to figure out how to change the font-style/font-weight (or any other global properties except the color) for the entire app, dynamically on the fly.
For Example:
We have a vue application running and the global font is currently set to Roboto,
What I want to do is provide a list of available fonts in a v-select and dynamically feed the selected value(suppose Raleway) in the variables.scss file or somehow trigger Vuetify to pick up the updated font-family (even other customizations), and change the default font to Raleway for the entire application.
I don't want to add classes everywhere. It won't be maintainable.
Any ideas on how can this be achieved?
Thanks in advance!
Changing the font app-wide is possible through the variables file as you mention, but this is a build-time decision. If you're wanting the user to swap out the font in the running app, there isn't any mechanism for this as far as I know, because the app is already compiled and running.

We are working on a React application (using Create React App without ejecting it) and we decided to use Ant as our base component library.
Now that we are near the end of the project, we discover that the application will be integrated into a corporate portal (WebSphere) as a "portlet", so we inherit all the CSS files from the main page.
Both frameworks seem to have their own reset styles, but they use different values.
So far, I have not been able to find a LESS variable in Ant that can be used for prefix all Ant's CSS rules.
Has anyone ever tried to make them live together?
We don't own the parent development, we can only make change on the React part, so only things related to Ant.
We finally go with a specific CSS patch file, and we add rules when needed.
Not really perfect, but none of the suggested path did the job we expected.
Here you can see some of the default antd variables.
One of them is #ant-prefix: ant;. I think you can change it and apply different styles.
That is a tough one, and at the end of development no less!
As #froston mentions, and which you seem to have tried the #ant-prefix: ant; in addition to this you will need to se prefixCls as a prop on every component instance you create, which will definitely be an exercise in self-flagellation.
Even if you set a global CONSTANT and import and use this with your components, you still have to thread it through to all the places, and will need to be appended with the component name.
By way of example, the defaultProps for an anchor is prefixCls: 'ant-anchor'.
Hope this helps and good luck!
Is there a way to apply different styles depending on the operation system? How does one define separate themes for Windows, macOS and Linux?
There is currently only one "default" theme, platform-specific themes are planned, but not yet implemented.
If you want per-platform themes/styles, you need to add them to your Application.Styles manually inside Application.Initialize using StyleInclude class (See App.xaml from application template). For platform detection you can use AvaloniaLocator.Current.GetService<IRuntimePlatform>().GetRuntimeInfo().OperatingSystem.
I recently started to create custom theme for ExtJS 5 by Sencha.
Following http://docs.sencha.com/extjs/5.0.0/core_concepts/theming.html I managed to create ThemeDemoApp, inherit ext-theme-neptune, change $base-color to green and refresh/rebuild ThemeDemoApp with my-custom-theme. All ok.
My problem is, ThemeDemoApp is quite poor for testing a custom theme. A panel, tab, button and a modal window. That's it?
After bit of googling I bumped into http://dev.sencha.com/ext/5.0.0/examples/themes/index.html. (Why isn't this mentioned in the guide?!) Heading says: View and test every Ext component against bundled Ext Themes, or your own custom themes.
My question is: How? How do I test my own custom theme against this example? Do I have to dig into the source (themes.js) and build such page/application myself?
The examples - including the Theme tester - is included in the ExtJS download.
You can modify the list of themes available by editing the shared/options-toolbar.js file.
To get it to find your theme, you'll either need to name it similar to the others (ext-theme-name), or modify themes.js accordingly.
Or you could just hack the theme.js file to hardcode your theme.
(Ext JS 4 used to create an example page for themes automatically - it doesn't seem to do that now, though)
According to advice at How do I include a JavaScript file in another JavaScript file? I decided to load both options-toolbar.js and themes.js (with just minor modification - commenting out Ext.onReady(...) function in themes.js) and I used functions getBasicPanel(), getCollapsedPanel(), etc. in my own application to create the same testing page (absolute-layout container that fits the page).
Anyhow, I guess Robert's answer is the correct one - there is no prearranged, ready-to-use functionality from Sencha :-(
While searching for a method to determine which theme is currently in use for Windows 8, I came across this article. It states that the theme is set per application and cannot be changed. I didn't realize that this was the case, nor did I do anything to set my theme to "Dark" (although it seems to be so). If this is correct, then how is the app theme set or, if not, how can I determine which theme is currently in use?
By default new applications use the "Dark" theme, this is set by a property called RequestedTheme on the Application object. To change to the "Light" theme you can set the property in the App.xaml file on the Application element. You can read that same property to determine which theme isn't being used, but since it cannot be changed by the user it's value will only ever be what you set it to be.
I'm re-creating an AIR app with FB 4.5.1. (I've started from scratch, having had trouble importing FB 4 projects).
In the app.xml I have the following defined:
<systemChrome>none</systemChrome>
<transparent>true</transparent>
Having done this I still get a full window with titlebar, min, max, and close buttons.
what gives?
I believe you need to create a skin for the application.
This appears in Adobe's forum, and includes an FXP of a functional transparent app:

Setting systemChrome & transparency along with "backgroundAlpha" to "0" would have helped in Flex 3.
But, skinning of components in Flex 4 i.e Spark components is little different and completely customizable.
Following are the steps you need to do make the window transparent.
Set systemChrome to "none" in the XML configuration file
Set transparent to "true" in the XML configuration file
Copy the skin code from <SDK_FOLDER>\frameworks\projects\airframework\src\spark\skins\spark\S parkChromeWindowedApplicationSkin.mxml and paste in a new MXML file.
Set the "alpha" property of "backgroundRect" object inside the skin file to "0".
Assign the newly created skin as the "skinClass" for "s:WindowedApplication" object
Please import the attached FXP file using "File->Import Flex Project" menu and have a look at the code to make it much more clear.
First, I discovered it is easier to interact with app.XML by opening it via "Open With -> Text Editor".
Second, and this is really embarrassing, I had simply failed to remove the comments bracketing
was:
<!-- <systemChrome>none</systemChrome> -->
<!--<transparent>true</transparent>-->
should have been:
<systemChrome>none</systemChrome>
<transparent>true</transparent>
...duh! I knew better, but...
Lastly, for a completely chromeless app, add
showStatusBar="false"
to the app header.
that's it!
