Customize Button appearance

[Manoiud]

Hello, I’m a new user. Loving the app so far, and it’s fun to program in BASIC again, especially with all the upgrades.

One question: is it possible to customize UI elements with custom graphics? Like having an image as the button texture and maybe even changing the font and color of the button text?

Thank you!

[Mr. Kibernetik]

No, buttons cannot have graphics as their component.

But buttons can be transparent to display image below the button. Or sprites can be used as an interactive images.

[Manoiud]

Thank you for the suggestions for a workaround, will do that.

How to set a button transparent? Can not find this in the manual of Mr. Dutchman.

Here's a program that Rbytes made as a demo for using icons as text in buttons:

Code: Select all

/*
After finding that emoji could be used to design a clickable list, I wondered if they might be also be useful as pushbutton switches. The answer is yes. I could have condensed the code by using a loop, but I left it expanded so that all you need to do to use a button in your own programs is to copy and paste its code section.
The first two buttons toggle on-off only. The next two have an off-low-high sequence.

I really like the functionality this program would add to a few projects I'm working on, but when I copied the program and ran it none of the emojis showed up. I am running this on an iPad 9th gen with IOS 17.6.1.

I couldn't find a way to post a photo, but my screen appears like this (if I tap above each of the OFF words, where I'm guessing the emojis appear, OFF changes to ON on the 1st 2, and LO HIGH on the last 2). How to I get the emojis to appear?

EMOJI SWITCHES


OFF OFF OFF OFF

[Mr. Kibernetik]

In the program sample above, instead of

Code: Select all

DRAW ALPHA 0

there should be

Code: Select all

DRAW ALPHA 1

or just remove this line.

[Mr. Kibernetik]

This is a simple example of two buttons, one is default and another one is transparent:

Code: Select all

graphics
graphics clear 0,1,1
fill alpha 0
draw alpha 1
draw color 0,0,0

button 1 text "button 1" at 100,50

set buttons custom

button 2 text "button 2" at 100,100

Thank You!

Example of Rbytes:

"SET ORIENTATION LANDSCAPE" will persist also for other programs until SmartBasic (v6.9 IDE on iPhone 13 pro) is completely finished or "SET ORIENTATION 0" is applied as a single task or added and run in another program?

[Chooch912]

Thank you Mr. K.

Changing to DRAW ALPHA 1 solved the problem and the program works like a charm.

Also, I appreciate your "simple" 2 button program. I now have a better understanding of "transparency".
