Hi Gordon

Is there anything this extension can do that I can't already do with App Inventor's existing blocks?

  • For FontTypeface, I haven't (yet) seen blocks to set this for the built-in system.

  • For FontBold and FontItalic, some components have the set FontBold blocks, such as Button, but some do not, such as TextBox. Here is a list:

For all components that have the FontBold/FontItalic blocks (7)

  • User Interface: Button, DatePicker, ListPicker, TimePicker.

  • Media: ImagePicker

  • Social: ContactPicker, PhoneNumberPicker

For all components that do not have the FontBold/FontItalic blocks (6)

  • User Interface: Checkbox, Label, PasswordTextBox, Switch, TextBox.

  • Social: EmailPicker.

All "Buttons" have the FontBold and FontItalic features, while all "TextBoxes", Check boxes and Switches do not.

Some of the most popular components, e.g., Label, TextBox, do not have the function to settle FontBold, FontItalic and FontTypeface natively, so I made this extension.

This extension adds storage permission in manifest or not?

No, why would it add permission in Manifest? It is just an extension to set the font among 4 options, which is in the Android class Typeface, so it does not acces the storage system.

You can always go to GitHub and review the source code of the extension. No libraries, no extra permissions, only the 4 built-in fonts.

Ok thank you was asking coz myfonts adds storage permission to manifest.

Yes but with MyFonts extension you can add any custom font instead with this extension you only have the ability to set properties for default fonts used by MIT App Inventor from blocks

But that permission is useless when I upload my font in assets

There are a lot of types of "Serif" fonts online that you can find. The "Serif" block in this extension uses the default Serif font of Android. The "Serif" font sets this property dynamically, because currently, there is not a feature to do this.

Well of course they can be via the Designer palette, you mean they do not have the same attribute settings via Blocks, so your extension is fixing that anomaly.

This extension allows the developer to set some basic font settings via Blocks for individual Components. Works well in my test, on App Inventor nb188a.

It only supports these components because technically, these components are all "TextView"s (they are all sub-classes of the android.widget.TextView family). I'm still finding a way to change the ListView fonts.

Have you found a way to change listview fonts?
I am still waiting for your listview fonts aix. :wink:

ListView is a bit different. It is a special library (I think), so it might be impossible to do that. But Iโ€™ll check on that.

You should see the source code :

It might be possible.
