Good Morning. Keith



Continuing the work of the MVP-50T, within my programming limitations, which I am gradually becoming familiar with, the menu is fully functional as far as Canvas is concerned. However, a task that I thought was simple, I am not achieving full success, which is the question of the visibilities (false or true) of the scripts of each canvas, which at first did not find a way to work. For example, the same Text that I insert on canvas 1 appears on all the others and vice versa, even if I give the conditions true or false on each one of them. Is there an explanation for my failure? If anyone in our community has had this issue and it has been resolved, I would appreciate it if you would direct me to the right forum topic.

Thank You


Marcio

Hi,

Not sure. Can you post a short script that demonstrates the issue.

I understand that I need to use a _txt before inserting a text in a specific Canvas(blue), without it being seen in another Canvas(yellow) that is in sequence in the menu. However, I am not able to use a function like _txt. Is there any function format that finction inside a canvas with the reuisito _txt?


txt_hoobs_hours2 = txt_add("000", "font:Oita W01 Cond Bold.ttf;size:36px; color:white; halign:right;", 108, 275, 90, 28)
-----
visible(txt_hoobs_hours2, false)

canvas_draw(system_canvas, function()


_rect(0,0,451,488)

_fill_img("system_screen_short.png",0,0,451,488)

function hoobs2(mts)

txt_set(txt_hoobs_hours2, string.format("%01.01f", mts) ) -----------------------------This way it works --- but it appears in all canvas
_txt(txt_hoobs_hours2, string.format("%01.01f", mts) ) -----------------------------This way not works

visible(txt_hoobs_hours2, true)


end

Hi,

Use _txt() within a canvas_draw()

Else your txt_add() ID <txt_hoobs_hours2> needs to be in a group which which you make visible or not.

Thank you very much!!

Please, just tell me what I did wrong.

Thank for the patiente.s

Please next time put your script between code brackets. The </> button.

Your text item in the canvas is wrong:

[Keith Baxter]

Hi,

Your issue is that you are using your text_add() as a var within a canvas_draw()

The text_add() will always be visible. If you want to use text_add() then you have to manage the text_add() visibility. Adding the text_add() node into a canvas_draw() node only invites the value. Not the visibility of the node.

It is best to use _txt() within canvas rather than the the text_add() var.

I wanted to demonstrate all those features.

@Ralph indicates correct.

Good Morning.

Could you please point me out where I'm wrong?

Thanks
