problem with the card and the Browser

[ferrandjames]

Hello, I just put a browser on a Card2 but when I put a button back on a card1, the browser still appears on the card1, how it should not appear on card1?

Hi James,

a "browser" object is always an OVERLAY on the screen and not a "real" LiveCode object.
This way this object will always be on the screen, does not care about stacks and cards
and will leave the responsibility to YOU, the developer

You will need to hide or close (delete) the browser when switching cards/stacks!

Hi James,

newbie or not, as I wrote in my last mail, you can find the answer in teh LiveCode menus!

EDIT:
Here some nore hints:
...
## Delete the iOS object:
iphoneControlDelete id
...
## Change its visibility:
iphoneControlSet id, "visible", false
...

I created a button function as return, and I have write code like "iphoneControlDelete isBrowserId" and its not working ... I do not understand ...

[Klaus]

Hi James,

please post the script(s) that you use to CREATE the browser on iOS!

You may need to declare the object ID as a global variable to be able
to use it with "iPhonedelete ID" or "iphoneControlSet id,..."

the code of the cards of browser :

# declare the local id of the browser we are creating
global sBrowserId

# when the card is opened make sure that default settings are configured
on preOpenCard
# quit if we are not on a mobile device
if the environment is not "mobile" then
exit preOpenCard
end if
# create the browser
iphoneControlCreate "browser"
put the result into sBrowserId
# set up the basic defaults
iphoneControlSet sBrowserId, "rect", the rect of group "Browser"
iphoneControlSet sBrowserId, "visible", "true"
iphoneControlSet sBrowserId, "url", "url-of-google-example"
end preOpenCard

on closeCard
if the environment is not "mobile" then
exit closeCard
end if
# destroy the browser we created
iphoneControlDestroy sBrowserId
iphoneControlDelete sBrowserId
end closeCard

# provide a status message that indicates loading has started
on browserStartedLoading pUrl
put "Started loading:" && pUrl into field "Status"
end browserStartedLoading

# provide a status message that indicates loading has finished
on browserFinishedLoading pUrl
put "Finished loading:" && pUrl into field "Status"
put pUrl into field "Url"
end browserFinishedLoading

# provides a status message that indicates the reason for loading
on browserLoadRequest pUrl
answer "Do you want to load:" && pUrl with "Yes" and "No"
if it is "Yes" then
pass browserLoadRequest
else
put "Refused:" && pUrl into field "Status"
end if
end browserLoadRequest

# a handler that executes an action invoked by the controls
on doAction pAction
iphoneControlDo sBrowserId, pAction
end doAction
# a handler that loads the URL
on goUrl pUrl
iphoneControlSet sBrowserId, "url", pUrl
end goUrl

and i have a create a button with this code :

on mouseUp
iphoneControlDelete sBrowserId
#iphoneControlSet sBrowserId, "visible", false
end mouseUp


its still not working ...

Hi James,

the problem is the ID that you get when you initialize (create new) browser control.
It IS already declared as a global variable, but you need to declare it every time in every
scripts/handlers you use this variable!

Do this:

Code: Select all

on mouseUp
   GLOBAL sBrowserId
   iphoneControlDelete sBrowserId
end mouseUp

That should do the trick!
