Collapse and expand Tree View Widget from code

Re: Collapse and expand Tree View Widget from code
That is not possible as a single command in the current implementation. You can get the fold state array and then create one that will have everything expanded. Since the widget constructs the fold state array in a lazy manner (only adds keys as they are visited and unfolded) and the entire tree is not parsed initially depending on size, adding it to the widget will take a bit of code. Probably a good Hacktoberfest addition.

Re: Collapse and expand Tree View Widget from code
Here is one solution for expanding a tree completely, up to six levels. There may be a way to do it recursively but this solution has the advantage of avoiding a headache.
Code: Select all
on unfoldEntireTree pWidgetID,pCardNumber,pStackName
lock screen
local pFoldArray,tK1s,tK2s,tK3s,tK4s,tK5s,tK6s,tK1,tK2,tK3,tK4,tK5,tK6,tL,pData
put the arrayData of widget id pWidgetID of cd pCardNumber of stack pStackName into pData
repeat for each key tKey1 in pData
put false into pFoldArray[tKey1]["folded"]
put the keys of pData[tKey1] into tK1s
repeat for each line tK1 in tK1s
if pData[tKey1][tK1] is not an array then
next repeat
else
put false into pFoldArray[tKey1]["array"][tK1]["folded"]
put the keys of pData[tKey1][tK1] into tK2s
repeat for each line tK2 in tK2s
get pData[tKey1][tK1][tK2]
if it is not an array then next repeat
else
put false into pFoldArray[tKey1]["array"][tK1]["array"][tK2]["folded"]
put the keys of pData[tKey1][tK1][tK2] into tK3s
repeat for each line tK3 in tK3s
get pData[tKey1][tK1][tK2][tK3]
if it is not an array then next repeat
else
put false into pFoldArray[tKey1]["array"][tK1]["array"][tK2]["array"][tK3]["folded"]
put the keys of pData[tKey1][tK1][tK2][tK3] into tK4s
repeat for each line tK4 in tK4s
get pData[tKey1][tK1][tK2][tK3][tK4]
if it is not an array then next repeat
else
put false into pFoldArray[tKey1]["array"][tK1]["array"][tK2]["array"][tK3]["array"][tK4]["folded"]
put the keys of pData[tKey1][tK1][tK2][tK3][tK4] into tK5s
repeat for each line tK5 in tK5s
get pData[tKey1][tK1][tK2][tK3][tK4][tK5]
if it is not an array then next repeat
else
put false into pFoldArray[tKey1]["array"][tK1]["array"][tK2]["array"][tK3]["array"][tK4]["array"][tK5]["folded"]
put the keys of pData[tKey1][tK1][tK2][tK3][tK4][tK5] into tK6s
repeat for each line tK6 in tK6s
get pData[tKey1][tK1][tK2][tK3][tK4][tK5][tK6]
if it is not an array then next repeat
else
put false into pFoldArray[tKey1]["array"][tK1]["array"][tK2]["array"][tK3]["array"][tK4]["array"][tK5]["array"][tK6]["folded"]
end if
end repeat
end if
end repeat
end if
end repeat
end if
end repeat
end if
end repeat
end if
end repeat
end repeat
set the foldState of widget id pWidgetID of cd pCardNumber of stack pStackName to pFoldArray
end unfoldEntireTree
Re: Collapse and expand Tree View Widget from code
Or here's the same solution but much shorter and faster, come to think of it:
Code: Select all
on expandEntireTree pWidgetID,pCardNumber,pStackName
lock screen
local pFoldArray,tK1s,tK2s,tK3s,tK4s,tK5s,tK6s,tK1,tK2,tK3,tK4,tK5,tK6,tL,pData
set the foldState of widget id pWidgetID of cd pCardNumber of stack pStackName to empty
put the arrayData of widget id pWidgetID of cd pCardNumber of stack pStackName into pData
repeat for each key tKey1 in pData
put false into pFoldArray[tKey1]["folded"]
repeat for each key tK1 in pData[tKey1]
if pData[tKey1][tK1] is not an array then
next repeat
else
put false into pFoldArray[tKey1]["array"][tK1]["folded"]
repeat for each key tK2 in pData[tKey1][tK1]
if pData[tKey1][tK1][tK2] is not an array then
next repeat
else
put false into pFoldArray[tKey1]["array"][tK1]["array"][tK2]["folded"]
repeat for each key tK3 in pData[tKey1][tK1][tK2]
if pData[tKey1][tK1][tK2][tK3] is not an array then
next repeat
else
put false into pFoldArray[tKey1]["array"][tK1]["array"][tK2]["array"][tK3]["folded"]
repeat for each key tK4 in pData[tKey1][tK1][tK2][tK3]
if pData[tKey1][tK1][tK2][tK3][tK4] is not an array then
next repeat
else
put false into pFoldArray[tKey1]["array"][tK1]["array"][tK2]["array"][tK3]["array"][tK4]["folded"]
repeat for each key tK5 in pData[tKey1][tK1][tK2][tK3][tK4]
if pData[tKey1][tK1][tK2][tK3][tK4][tK5] is not an array then
next repeat
else
put false into pFoldArray[tKey1]["array"][tK1]["array"][tK2]["array"][tK3]["array"][tK4]["array"][tK5]["folded"]
repeat for each key tK6 in pData[tKey1][tK1][tK2][tK3][tK4][tK5]
if pData[tKey1][tK1][tK2][tK3][tK4][tK5][tK6] is not an array then
next repeat
else
put false into pFoldArray[tKey1]["array"][tK1]["array"][tK2]["array"][tK3]["array"][tK4]["array"][tK5]["array"][tK6]["folded"]
end if
end repeat
end if
end repeat
end if
end repeat
end if
end repeat
end if
end repeat
end if
end repeat
end repeat
set the foldState of widget id pWidgetID of cd pCardNumber of stack pStackName to pFoldArray
end expandEntireTree
Re: Collapse and expand Tree View Widget from code
TL;DR - but if you're looking to collapse all, this has worked for me in the past, but admittedly this is only for a tree widget with 1 level, i.e. no sub-arrays:
to expand all:
Just rechecked and it does work for my purposes, hopefully this may help...

Code: Select all
set the foldState of widget "<tree widget name>" to falseCode: Select all
command expandAll pTree //long id of the tree widget
local tNewState
get the keys of (the arrayData of pTree)
repeat for each line tLine in it
put false into tNewState[tLine]["folded"]
end repeat
set the foldState of pTree to tNewState
end expandAllBW
