Hi everyone,

I'm trying to make an extension script, at some point when the user clicks a button, a prompt box should appear asking him for some input text, that is then used in the script.
However, when it gets to initiating the prompt box it doesn't show up:
here's the snippet I am working on:

Code: Select all

function createGUI()
main_layout = vlc.dialog("Caption tracker")
 -- some GUI widgets
capture_moment_b = main_layout:add_button(" Capture Moment ",capture_moment,1, 4, 1, 1)

end

function capture_moment()
  --some logic statements
       prompt_caption()  
 end
 

 function prompt_caption()
 -- vlc.msg.dbg("here")
  prompt_box = vlc.dialog("Moment's caption")
  prompt_text_input = prompt_box:add_text_input("Enter caption!")
  confirm_caption_b = prompt_box:add_button("caption recorder",confirm_caption)
  prompt_box:show()
 
 end

When I switched to debugging mode, the script made it to "here" string, then nothing happens.
I'm using VLC 2.1.5
So, is there a way to prompt some user's input ?
also, is there a way to disable text inputs, buttons, other widgets ? it should be a no brainer but , weirdly, I can't find a 'set_enabled' function.

lua warning: Error while running script ... ... Only one dialog allowed per extension!

You can delete the current dialog and create another one or you can add and delete widgets in the current dialog and thus keep its position on the screen. As stated in the README document:

d:delete(): Close and delete this dialog.
d:del_widget( widget ): Delete 'widget'. It disappears from the dialog and repositioning may occur.

thanks mederi for your reply, figured out lately that I can't have but one dialog per extension

so I decided to go with your advice, delete dialog and create another one, however, while trying to create the second dialog VLC suddenly crashes (actually the dialog appears in VLC, then VLC crashes immediately)
I've opened the debugger, and it seems that VLC needs some time to delete the first dialog before trying to initiate another one so it crashes, here is the log:

Code: Select all

lua debug: Deleting dialog "moments tracker"
lua debug: waiting for the dialog to be deleted
qt4 debug: Deleting extension dialog 'Moments and checkpoints tracker'
lua debug: creating dialog 'Enter Moment's capture'
qt4 debug: creating a new dialog 'Enter Moment's capture'

is there a way to halt the creation of new dialog till the first one is completely deleted or a way to check the status of the first dialog ? or I do have another problem ?

Thanks again

Try this one:

Code: Select all

function descriptor()
	return {
		title = "test - Another dialog loop",
	}
end
function activate()
	Create_dialog()
end
function deactivate()
end
function meta_changed()
end
function close()
	vlc.deactivate()
end
-------------------------

function Create_dialog()
	if d then
		text=input:get_text()
		d:delete()
		--d=nil
	end
	d = vlc.dialog(descriptor().title)
	input = d:add_text_input(text or "Hello",1,1)
	d:add_button("Next dialog", Another_dialog,1,2)
end

function Another_dialog()
	text=input:get_text()
	d:delete()
	--d=nil

	d = vlc.dialog("Another")
	label = d:add_label("Previous input text:",1,1)
	input = d:add_text_input(text,1,2)
	d:add_button("Previous dialog", Create_dialog,1,3)
end
