dgHilitedLine Function

[Babyprincess]

Hi,

I am having a problem with this function. I managed to place my images in a datagrid, but the images are not displayed as thumbnails, they are just the various jpg file name. I am trying to use this function, so that when i click on one image name, the image would appear on the image area. Below is my code & i can't seem to see whats wrong. Please help me. This is the code in my button. Can someone guide me on how i can do this function.

on mouseUp
local tFolder

put field "Folder" into tFolder
set the defaultFolder to tFolder
put the files into x
set the dgText of group "Data Grid" to x

if pBtnNum is 1 then
put the dgHilitedLines of group "Data Grid" into theLine
put the dgDataOfLine[theLine] of group "Data Grid" into theDataA
put the dgDataOfLine[theLine]of group "Data Grid" into img "ImageArea"
answer theLine
end if

end mouseUp

Hi.

The "files" returns a list of files in the defaultFolder. A dataGrid, when setting the "dgtext" is going to look for a tab and return delimited dataSet. I use dataGrids for simple text, but am no expert with datagrids that use images and other complex gadgetry. I suspect, though that your DG is simply doing what you told it, loading a return delimited list into the first column. And this assumes that you loaded your defaultFolder (tFolder) with a valid pathname.

Is it really neccessary to populate the datagrid every time when the user clicks?

Oh...errr...
This is for Android?
Well the path would be for the first item in your list:
c:\user\admin...\IMG-2013....jpg
so in the group DataGrid 1: -- if you didn't change it's name

Code: Select all

on mouseUp
   put the dgHilitedLines of group "DataGrid 1" into theLine
   put the dgDataOfLine[theLine] of group "DataGrid 1" into theDataA
   combine theDataA with space
   put theDataA 
-- set the filename of image "the image name" to field "the path shown in your image" & theDataA 
end mouseUp

Not sure if this will work on mobile at all.

EDIT: -- set the filename of image "the right hand image in your pic" to field "the path shown in your pic" & theDataA
Just trying to be clear
