Button
Custom: Icon, Radius, Border, Color, Gradient, HTML Text, Text Alignment.

Some sample screenshots

---

CornerRadius

Set corner radius for multiple buttons.

---

ButtonColors

Changes button colors dynamically.

Remember that you can put transparent buttons.

---

Image

Set image for multiple buttons with position and size.

In the name parameter you can put an empty text block and the button will not have an image.

Or you can add the image from assets.

---

Border

Set border for multiple buttons with color and width.

---

SetButtonShadow

Sets shadow behind the button.

Sets a list of lists with the values ​​for the shadow.

• I made the Shadow function to show in which position the values ​​go and for greater convenience.
  • But you can also pass just a list instead of the Shadow function.

Example of List

---

Shadow

Adds shadow to buttons.

Details

• color: Shadow color, in RGB, Hexadecimal or AI2 color blocks.
• spread: Shadow distance.
• offsetX: Horizontal offset of the shadow.
• offsetY: Vertical offset of the shadow.
• opacity: Opacity of the shadow, starting from 0.1.
• blur: It's recommended to set the value to 12.

It's recommended to set minimum values ​​so that the shadow is not too large, since it will make the button reduce its size taking its place.

---

RemoveButtonShadow

Removing the shadow increases the size of the button. Recommendation: If you add a shadow, don't remove it unless you configure the button correctly.

I have it in mind to fix it, but I don't know when yet.

---

SetHtmlTextWithAlignments

Add text in html and alignment.

Alignment options:
center, left, right, top, bottom.

• Screenshots with examples of buttons with and without HTML and alignment.
  And the button below with transparency.

Screenshots

---

Padding

Set padding for multiple buttons.

Default values:

• top: 16, bottom: 16, left: 40, right: 40.

Like all other parameters, if you set a single value, that value will apply to all buttons, or add a different value for each button in the list.

v1.0.3

Update v1.0.3
Mar 22, 2025.

• The buttonShadows parameter has been separated from the SetButton function.

• Helper blocks have been added for the imagePosition parameter of the SetButton function and the alignments parameter of the SetHtmlTextWithAlignments function.

• Previously, the button only accepted two input colors; you couldn't enter more or less colors without getting an error.

  • Now, the button can accept one color or more than two colors for a gradient.

• A function has been added to dynamically change the button's color.

• A function has been added to remove the shadow. (Removing the shadow increases the button's size.) Recommendation: If you add a shadow, don't remove it unless you configure the button correctly.

• A function has been added to add HTML text and alignment.

---

v1.0.4

v1.0.4 Ago 11, 2025.

• Functions separate from the SetButton function have been added, so the SetButton function will be removed.
• Now, when you put an empty text block in the imageName parameter, the button won't have an image added.

---

v1.0.5 Ago 12, 2025.

• The ButtonColors function had to come after any of the other functions to be applied correctly.
  • Now, calling the ButtonColors function first will apply it correctly.

---

• Added padding to center the text when the button is smaller, and added the function to control it.

Extensión: v1.0.4

If you're already using the SetButton function in your app, use this extension to manually migrate to the new blocks without crashing everything. You can then use the other extension below to update it, as it's lighter without the SetButton function.

If you are not using the SetButton function, you can use this extension directly without any problem.

v1.0.5
joejsanz.joedevbutton.aix (14.6 KB)

Note:

• You don't need to use the Image function if you're not adding an image to a button.
  • The same goes for any other function.

Thanks

[uskiara]

Awesome extension !

[Joejsanz]

Thank you so much @uskiara

[HarshVardhanSolanki]

Nice extension, It will help us alot in UI enhancements.

[Joejsanz]

Thank you so much @HarshVardhanSolanki

[HarshVardhanSolanki]

I give you a suggestion, register button aside not with the main component, use id feature in the main block, it will help user to register button or buttons in two, but designs in a one.

1. Register single button block

2. Register Buttons list block

3. SetShadow for list

4. SetShadow for button

I hope you got my points.

[Usane]

Fantastic! Finally customized buttons. Thank you.

[Joejsanz]

@HarshVardhanSolanki

@Joejsanz

Note: This shadow is for the button text.
For the shadow that goes under the button, I'm still working on it.

I had already implemented the shadow behind the button, but I removed that function because when clicking the button, the shadow disappeared, then I managed to make it stay, but I had to remove the interaction of the button with the native events of App Inventor.
So for now the shadow will have to wait a bit.

• This is a look at what was done, the shading is very faint but it looks good.....

@HarshVardhanSolanki

use id feature in the main block

About using ID in the block, it would be nice if I created some events to identify which block was clicked, but I don't have any events created, since this extension works with App Inventor's native events.

Or I don't know if you mean something different and I misunderstood.

@HarshVardhanSolanki

• Register Buttons list block
• SetShadow for list

I imagine you suggest the list of buttons to put the same style on that list and not use too many blocks?

[Joejsanz]

Thank you so much @Usane

[HarshVardhanSolanki]

@Joejsanz

I imagine you suggest the list of buttons to put the same style on that list and not use too many blocks?

Yes

[Kevinkun]

it will be better if the color socket can accept AI2 color.

[Joejsanz]

@HarshVardhanSolanki Your suggestion sounds good, I'll check that out.

[HarshVardhanSolanki]

Sure, Also Kevin's suggestion will very helpful after sockets accepts the Ai2 colors.

[Joejsanz]

@Kevinkun You're right, I'm going to implement that.

[Joejsanz]

Update:

@Joejsanz

Function inputs have been completely changed, they now accept lists of buttons and each parameter also accepts lists to individually configure each button, if you have a list of buttons with more than 1 button and in the parameters only the first button is configured, the other buttons will take those settings.

Color inputs now accept native App Inventor colors and colors in hexadecimal.

Dear @Usane,
while this extension is still really awesome and powerful (@Joejsanz don't stop to develop yours !!!) please do not forget these two:
@gordonlu310 's com.gordonlu.buttonicons.aix
and
@TIMAI2 's uk.co.metricrat.buttonmaticon.aix

Now we have a "big choice" for customizing buttons.
Great !

[HarshVardhanSolanki]

Great you listen, best you built.

[Usane]

You are right but, those are not focusing on shaping the button itself. For example I really missed the radius of the fillets. Now we have it. Now I miss the triangle, hexagon and star shapes, haha.

excelente
