Displaying the PDF within a Rev stack

[shalu]

Hi All,

I am using Linux system(64-bit Linux) and LiveCode version 8, My objective is Displaying the PDF within a Rev stack, so that I am use the following code

Code: Select all

global sBrowserId
on openCard
    browserOpen
end openCard

on browserOpen
    put the windowid of this stack into tWinID
    put revBrowserOpen(tWinID,"") into sBrowserId
    revBrowserSet sBrowserId, "showborder","true"
    revBrowserSet sBrowserId, "rect",rect of image "browser image"
end browserOpen
on browserClose
    revBrowserClose sBrowserId
end browserClose 


global sBrowserId

on mouseUp
    local tFile
    answer file "Please choose the file you would like to display" with type "PDF document|pdf|PDF"
    if it is not empty then
        put it into tFile
        browserSetURL tFile
    end if
end mouseUp

the browserSetURL handler is implemented in the card script

on browserSetURL pURL
      answer pURL
    revBrowserSet sBrowserId, "url", pURL
end browserSetURL

while executing the code I got the following error, How I solve this problem?

card "browserOpen": execution error at line n/a (External handler: exception) near "creation failed"

button "Browse": execution error at line n/a (External handler: exception) near "unknown browser id"

Thanks
Shalu

Hi Shalu,
first of all revBrowser doesn't work on linux, just on windows and Mac.
Probably you misunderstood the examplel, because on win or mac you should:

• put an image in the card, this image can be empty
• name it "browser image"
• put this code in the card:

  Code: Select all

  on openCard
      browserOpen
  end openCard
  
  on browserOpen
      put the windowid of this stack into tWinID
      put revBrowserOpen(tWinID,"") into sBrowserId
      set the bID of me to sBrowserId  #custom property
      revBrowserSet sBrowserId, "showborder","true"
      revBrowserSet sBrowserId, "rect",rect of image "browser image"
  end browserOpen
  
  on browserClose
      put the bID of this card into sBrowserId #custom property
     revBrowserClose sBrowserId
  end browserClose
  
  on closecard
    browserClose
  end closecard

• put a button in the card
• put this code in the button:

  Code: Select all

   on mouseUp
      local tFile
      answer file "Please choose the file you would like to display" with type "PDF document|pdf|PDF"
      if it is not empty then
          put it into tFile
          browserSetURL tFile
      end if
  end mouseUp
  
  on browserSetURL pURL
     answer pURL
     put the bID of this card into sBrowserId #custom property
     revBrowserSet sBrowserId, "url", ("binfile://" & pURL)
  end browserSetURL

On linux, to see a PDF, put a button in the card and put this code in the button:

Code: Select all

 on mouseUp
    local tFile
    answer file "Please choose the file you would like to display" with type "PDF document|pdf|PDF"
    if it is not empty then
        put it into tFile
        put  shell("evince " & tFile)
    end if
end mouseUp

Usually evince is default PDF viewer on Linux.
