Touch friendly UI --> Tree

[SayMaster]

Hi there,

I want to build a touch friendly UI with LV2023 Fuse Design System.

 

Is there a way to make a tree element touch friendly? especially enlarge the "+"/"-" for Expand/Contract elements?

 

 

Thanks in advance

No way to enlarge anything on the LabVIEW tree controls.  Best Bet for what you need is to use a .net Treeview control.  You can have custom sized images etc. but there is a somewhat steep learning curve and using .net in labview results in messy block diagrams with all of the references that have to be opened and closed etc.  There are examples on LAVA and ni.com.

You can also add additional controls for things like a dedicated set of booleans for expand or collapse, and move the selection up or down.  Not elegant for sure.  You can increase tree control fonts, and that helps with selection, but glyphs and other elements won't change in size.  I did make an idea exchange for it.

thanks guys!

that's what I feared 😕

 

 

I also found the .net solution but I am afraid to use it. The whole program is pretty old and I just did some performance tweaks for the update process (there are 1200+ elements in the tree and I changed the update process to only update visible elements)

 

probably wont touch this for the next years
