Will we be able to see the toggle-switch module in LuaRT soon ?

Samir

Hi Coskun,
What do you mean by toggle-switch module ?

cos00kun

Samir

ui module is based on Windows API common controls, which don't provide such widget (the equivalent are the Radiobutton or Checkbox widgets).

I am currently working on a new module which will implement a new widget. I can't talk too much about it right now but it will provide a whole new dimension for desktop application development 👀👀

cos00kun

yeah thanks. Good lucky for your new widget 🙂

How can I open [Login to see the link] webpage in internet browser when I onClick on a Label in my offline Wordell program?
I looked here [Login to see the link] but couldn't get this to work on the GUI

Samir

Use a onClick event like this one:

function button:onClick()
   sys.cmd('start "" "https://www.luart.org" ')
end

It should open a new browser window with the provided URL.

I think I'm pretty sure about the problem now. When I press the button, the color of both boxes should be the same, but strangely, it is not the same color.

local ui = require "ui"

win = ui.Window("Deneme",300,300)
labelA = ui.Label(win,"",100,100,40,40)
labelB = ui.Label(win,"",150,100,40,40)
buton = ui.Button(win,"Bas",100,30,70,30)
labelA.bgcolor = "0x6AAA64 "

labelB.bgcolor = labelA.bgcolor

win:show()

function buton:onClick()
 labelA.bgcolor = "0xF24765"
	labelB.bgcolor = labelA.bgcolor
end

repeat
	ui.update()
until not win.visible

I have found the bug. It's now fixed.
Thank you again Coskun.

cos00kun

when will the update be released 😀

Samir

I'm still trying to fix other bugs. I hope to release LuaRT 1.3.2 on sunday 👌

Samir
I can't wait. 🙂

Let's relax a bit. Now let's talk about Samir.

Who is Samir? (Where he lives, where he works, Age e.t.c)
Why did Samir choose the Lua language? Why Lua when there are so many popular programming languages?
How much further do you plan to develop LuaRT? Will you ever give up on this and turn to other programming
languages?
What are Samir's other hobbies?
Are you also interested in the C++ language?
If you think this site is only about "Luart" and you don't want to answer, I understand. 😃

cos00kun Let's relax a bit. Now let's talk about Samir.

I don't like to talk about myself too much, so it's going to be complicated !

cos00kun Who is Samir? (Where he lives, where he works, Age e.t.c)

I'm just a self-taught programmer who lives in France, with a job, wife, children (a classic life !)

cos00kun Why did Samir choose the Lua language? Why Lua when there are so many popular programming languages?

languages?

I love Lua simplicity, both from the programming language and from the implementation side of the virtual machine.
I hate programming languages that depend on heavy runtimes (.net I'm thinking of you there) or that produce multi-megabyte executables (hi Rust!) : simplicity and lightness have always been my goals when I code.

LuaRT is a project that I have been thinking about for a long time and which tries to solve two pitfalls when developing in Lua:

The absence of an ecosystem which leaves the door open to multiple modules/libraries without consistency
The need to master the C language and the compilation process / the LuaRocks package manager (a pain on Windows !)
Lack of real Windows support (I've even discovered how Lua developpers can be true Linux fanboys!)

I have a lot of ideas to develop LuaRT and provide more functionalities... I can't talk too much now 🙃

cos00kun Are you also interested in the C++ language?

I don't really like C++: the object overlay is not very easy to understand. The standard library is getting heavier and heavier (try compiling a static C++ program, without dependencies...)
But I don't rule out using C++ to develop modules for LuaRT, as the LuaRT API can be used in C++

cos00kun

Hmm thank you [Login to see the link]
I have a life like you. I have a family with children and a wife 🙂 Simplicity and clarity is the way I prefer, that's why I love the Lua language. LuaRT really created GUI for Lua language so thank you very much and I am very happy. When the "find the word" program is finished, I want to test all modules related to "ui" in LuaRT one by one and list the bugs if any. You can use me as a tester 🤭 Then I want to produce a much larger project, I'm thinking for now.

Samir

Thank you again for your help Coskun !

Samir

LuaRT 1.3.2 is released !
Thank you all for your help and bug reports 👏 👏

cos00kun

thank you!!!!!! 👏👏👏👏

.....
label.textalign="center" 
.....

the word inside a "label" object becomes "center" only in the X direction.
Let me explain a little more;
Let's say I define a 50 x 50 Label and I'm going to print the letter "A" in size 14. When I run the code above, the letter A is only aligned in the X direction whereas it is not aligned in the Y direction.

Samir

Ok Coskun I will check this.
It might be possible to center text label verticaly
