CREATING AN APP USING TOUCH EVENTS

The Magic_Pad app lets you draw with your finger, change colours and reset the screen like a

digital drawing book. It helps young learners practice drawing, handwriting and creativity while
improving hand control in a safe, educational way.
To create the Magic_Pad app, follow these steps:

Step 1 Create new project in the MIT App Inventor.

Step 2 Change the name of the screen to Magic_Pad in the Title textbox, adjust AlignHorizontal
to Center:3 and AlignVertical to Top:1 in the Properties pane.

Step 3 Click on the Layout component.
Step 4 Drag and drop HorizontalArrangement into the phone screen.

Step 5 Click on the User Interface component.
Step 6 Drag and drop Button1 into the HorizontalArrangement.

Step 7 Click on Button1 to edit its properties on the right-side panel: Text to Red, FontBold,
BackgroundColor to Red, FontSize to 20, Shape to Rounded and TextColor to Black.

Similarly, add Button2 and Button3 into the same HorizontalArrangement and set Text:
Blue and Green, BackgroundColor: Blue and Green, FontSize: 20 or larger, FontBold to
Checked, Shape: Rounded, TextColor: Black.

Step 8 Add Button4 from the User Interface drawer below the HorizontalArrangement.
