Hi Memam,
I understand you want to create the custom component based on Spinner of Appdesigner.
You can follow the below workaround to make the custom spinner.
- Open a new app in appdesigner.
- Drag and drop 2 "Button" components and 1 "Edit Field(Text)" component from the component library.
- Set the "Value" property to 0 of the "Edit Field(Text)" component.
- Fill the "Text" field of the "Button" component with upward and downward symbols.
- Create a callback function for the UP button, which increments the EditField.Value by one every time the up button is pressed. You can follow the code:
% Button pushed function: Button
function ButtonPushed(app, event)
currVal = str2double(app.EditField.Value);
newVal = currVal+1;
app.EditField.Value = num2str(newVal);
end
- Repeat the above step for the DOWN button, which decreases EditField.Value by 1.
- Position and resize the buttons and text components and run the app to see the result.
I hope the detailed steps help you.
Thanks,
Shivam
