[fpc-devel] Chosing a graphical interface for specific proposals

[luciano de souza]

It's really interesting. After looking for so libraries, it would be
fantastic to find a solution with tform. But, regarding everything
needs to be created only writing codes, without opening the
inaccessible interface of Lazarus, do you believe can it be done?

I give you an example using Lua.

require('iuplua')

label1 = iup.label{title = 'This is the text of label 1'}
button1 = iup.button{title = 'Button 1')
button2 = iup.button{title = 'Button 2')
button3 = iup.button{title = 'Button 3')
list1 = iup.list{'Option 1', 'Option 2', 'Option 3'; multiple = 'NO',
dropdown = 'YES', value = 2}

box = iup.vbox
{
iup.hbox{label1; border = 'NO'},
iup.hbox{list1; border = 'NO'},
iup.hbox{button1, button2, button3; border = 'NO'}
}

dlg = iup.dialog{box; title = 'Example of IUP library', gap = 5, size
= 'HALFxTHIRD'}
dlg:showxy(iup.CENTER, iup.CENTER)
iup.MainLoop()

function button1:action()
return iup.CLOSE
end

This code defines a pannel with a vertical box in wich is set three
horizontal boxes. The first one, with a label, the second, with a
combobox, and the third with three buttons. Some attributes were
defined and a callback for button1 click is also defined. And
everything only typing codes.

This is only an example. A sintax for C is also available and if it
was ported to Pascal, certainly the C sintax would prevail.

My question is: is it possible to create all the interface with tform
without using the Lazarus interfaces, in other words, only typing
codes in a text editor?
