I am just getting started with Xamarin Forms, so please excuse what may well be a rookie question...
I started out with a new Shell Forms App in Visual Studio, so some code was generated for me.
There is an AppShell page which contains a TabBar control. Inside this are Tab controls were I can set my ShellContent pages.
Each Tab has an Icon property, but this apparently only accepts PNG icons.
How can I use an icon font (which is already hooked up to display icons correctly as I am using them in the content of another page) for my Tab icons in Xaml?
I am using Xamarin.Forms 4.0.0.497661
You have to use FontImageSource to do that.
<Tab Title="MyTitle">
<Tab.Icon>
<FontImageSource FontFamily="{StaticResource IconFont}" Glyph="" Size="Small"/>
</Tab.Icon>
...
</Tab>
The solution below worked for me.
Copied the files from fontawesome inside Assets folder
fa-brands-400.ttf
fa-regular-400.ttf
fa-solid-900.ttf
Important the reference "Font Awesome 5 Brands" according to icon needed
<Tab.Icon>
<FontImageSource FontFamily="fa-brands-400.ttf#Font Awesome 5 Brands" Glyph=""/>
</Tab.Icon>
That's a great question. You can't use the tab icon property in a straight forward way to accept the icon font, unless you convert it into a PNG.
If you want to go that route, you can try this, you might have to deal with permissions for saving images. Worth a try!
You can do that with custom renderers as a workaround. Check this example on GitHub here: https://github.com/winstongubantes/Xamarin.Forms/tree/master/CustomIconizeFont

I am relatively new to the world of Xamarin.Forms and have a question with regard to Xamarin TableView.
I want to create a layout similar to the one shown below.
Question is, can I use TableView for this or is there an another option for this? Can anyone show this with XAML code please?
Thanks in advance.
Edit: Tabs in the bottom are not required.
I don't mean to be rude, but this is very easy to retrieve from the documentation pages and a bit of trying yourself.
To get you started, try this:
<TableView Intent="Settings">
<TableView.Root>
<TableView.Section>
<ImageCell Text="Invoice Customization" Source="Invoice_image.png" />
<ImageCell Text="Invoice Defaults" Source="Invoice_image.png" />
</TableView.Section>
<TableView.Section Title="Security">
<SwitchCell Text="Use Touch ID" />
</TableView.Section>
... etc.
</TableView.Root>
</TableView>
The arrows at the end of the cells and the footer text underneath the Security section are not possible with Xamarin.Forms out of the box, this will probably require you to write a custom renderer.
I have the following situation in Windows Phone 8.1:
Emulator with Dark theme
A Page Flyout
An element with RequestedTheme="Light" (inside a DataTemplate, in many pages)
This happens:
Open a flyout: it is Dark (as the app theme). Ok.
Navigate to a page that there is the element with RequestedTheme="Light". Ok.
Open a flyout: it is Light! Not ok!
Now all my Flyouts are Light. But my ApplicationTheme is still Dark.
It seems to be a bug.
Does anybody see if I am doing anything wrong?

Additional info: Flyouts doesn't have a RequestedTheme property, so I think it use the ApplicationTheme. But maybe there is something else.
I am using the popup menu in Extension Library like this
<xe:popupMenu id="pop">
<xe:this.treeNodes>
<xe:basicContainerNode image="/vwicn148.gif" label="Container">
<xe:this.children>
<xe:basicLeafNode label="Child" image="/vwicn148.gif"></xe:basicLeafNode>
</xe:this.children>
</xe:basicContainerNode>
</xe:this.treeNodes></xe:popupMenu>
And it look like this with an image added before the label
As my site is using only "font icons" from FontAwesome I want to display these instead of normal images. how can I do that?
You have 4 options (and they are not pretty):
use a custom renderer as Tim suggested
subclass the control so label is rendered passthrou
lobby the ExtLib team to add new properties
use an XSP.OnLoad script to add the font awesom tags
So, I'm trying to create a theme for Ninja-IDE. Ninja-IDE uses PyQt, so the themes are made in qss. I'm trying to make my Ninja-IDE look like VS2012. I was just wandering, if it is possible to have separate styles for horizontal and vertical tabs in qss.
QTabBar::tab:horizontal
isn't working for me.
Any Ideas?

I have this requirement where I have to change the default styles on my Ext JS application. I am not talking about changing stuff in CSS files yet. I am not that ambitious yet. Here is what I am looking for:
Suppose I need a Submit and Cancel buttons, I use xtype:button and text:Save ( or Cancel ). This will render buttons with the text on them. What should I do if I want to change the look and feel of the button? Or replace the button with a cool Save or Cancel image?
Right now I have all the texts on the application with the default font that ExtJS shows. What am I supposed to do if I want all the text on the application changed to a different font? Everything right from the data in forms/grids and the titles of each component should be changed to some other font my customer prefers. What am I supposed to do?
I understand these are very basic and a generic questions, but I am looking for a good headsup before I proceed with my task.
Thank you all in advance. Waiting for answers :)
Update: So, I found out how we deal with CSS and change the fonts. Can anyone help about the Chaning the look and feel for Submit/Cancel buttons.
I recommend you to use SASS and compass to build your own themes, or better said to change one the existing themes. In the Ext JS documentation you can find the css variables which you can set according to your needs.
If you are not ready for theming with SASS just yet take a look at this example of button configs from the sencha docs:
Stanadalone Example page: http://docs.sencha.com/extjs/4.1.3/extjs-build/examples/button/button.html
CSS that adds customized images to the buttons: http://docs.sencha.com/extjs/4.1.3/extjs-build/examples/button/button.css
JS that shows button configs: http://docs.sencha.com/extjs/4.1.3/extjs-build/examples/button/button.js
Essentially this shows how to use iconCls property on the button config along with a simple CSS class to add desired image to your button.
