Additionally/Sideeffects:
- Fix vstFreeNode to delete the item from the array, not only free the item itself
- Change/Rename GetSelectedNodesFromVT to GetVTCaptions and give it the ability to return all captions, not only the selected. This function is very useful now and saves writing much redundant code.
A table with 500 columns needed 3 seconds to display in the TSortListView, now that takes less than a half second.
Additionally/Side effects:
- TVTreeData structure moved to helpers.pas to be able to use it in new function GetSelectedNodesFromVT.
- ListTablesEditing dropped. We don't need to disable any shortcut there because there is none set.
- Avoid potential AVs when accessing not created items in TVTreeData.Captions
- Don't replace "ListProcessesSelectItem" by "ListProcessesClick". Do the menuitem stuff in popupHost.popup()
- Avoid potential AV when exceeding the captions-list of a node in GetNodeText.
This is the first VST and therefore some base procedures are added which can be reused for most other coming VT's:
- vstGetNodeDataSize
- vstGetText
- vstGetImageIndex
- vstHeaderClick
- vstCompareNodes
All these procedures should normally get linked to other VST's. Only the OnInitNode procedure cannot be reused, as it contains references to the data of the VST's nodes.
I hope the billions of options in this VST object make sense.
Left for later:
printlist.pas cannot process this list without changes. I will rewrite that as soon as all 5 lists are switched to VST.
