* Load in OnBeforePaint, if the tree's tag is set to NOTLOADED
* Load 1,000 rows in one step, up to a maximum of 100,000 rows. Both values are customizable.
* Load next chunk when user presses PageDown on the last node, or, more explicitly, when user clicks "Next rows" button
* Should fix all AVs which seem to be a timing issue with loading data on demand.
* Fixes issue #1675, fixes issue #1580, fixes issue #1721, fixes issue #1734, fixes issue #972
* Removes TNT Unicode controls, which are no longer required. All VCL controls now have native Unicode support.
* Remove Delphi 11 packages, otherwise we would either need to keep TNT or break Unicode
* PngComponents update from Uwe Raabe on http://cc.embarcadero.com/Item/26127
* Adjust auto build process
* Since Delphi 2009, Strings are now UnicodeStrings, not AnsiStrings any longer. Fix a bunch of compiler errors which came along with this change.
TODO: Project should compile but give tons of compiler warnings.
* Keep only one TRegistry object in memory instead of creating a new one in each routine.
* Move out relevant functions and TRegistry object from main to helpers to make them usable globally.
- Consequently use Mainform.GetRegValue() to read these values, an overloaded method with either Boolean, String or Integer result. These methods keep a global TRegistry object (regMain) open while the application runs, rather than creating a new one for each caller.
- Remove Mainform.SaveRegValue() which was used in one or two callers. Rather use a TRegistry object and do that by hand. There's no significant advantage in using a SaveRegValue method currently.
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.
