Awesome

Sample view on Android :)

About this port to Firemonkey:

What is working:

• it compiles under FMX - this was main task of this pull request;
• it draw tree nodes structure with apropiate levels;
• it draw nodes text with alignment;
• it draw buttons plus/minus (toShowButtons);
• it draw tree lines (toShowTreeLines), horizontal lines (toShowHorzGridLines), vertical lines (toShowVertGridLines), full vertical lines (toFullVertGridLines) (some pixel improvement needed but it is working);
• it support cliping during cell draw;
• it support multiple columns;
• it draw header columns.
• expanding, collapsing by mouse click.
• mouse cursor and header column resize by mouse.
• it accept focus, it draw focus rect and unfocussed rect, toExtendedFocus, toFullRowSelect, toHotTrack, toUseBlendedSelection.
• checkbox support system checkboxes (platform specific) + custom checkboxes.
• support for Android :)
• "hot" and "selected" plus/minus buttons.
• scrollbars/scrolling.
• toMultiSelect with smDottedRectangle and with smBlendedRectangle.
• mouse wheel scrolling
• it draw static background

What is not working yet:

• some mouse actions (drag/drop);
• clipboard;
• drawing tree border;
• drawing background tiled;
• some mouse actions on header;
• inplace editors;
• installing package for both VCL and FMX in the same time.

Current VT is derived from TRectangle. Will be good to have it as presented control with appropiate TDataModel. This will bring more possibilities like have e.g. 2 tree on the form based on same data. One will be i scale 1 second smaller in scale e.g 0.2 as a preview.

IMPORTANT.

To test FMX port of VT - you must add in the e.g. Delphi project->Options->Conditional defines VT_FMX. There is only package for Delphi Tokyo (but you can test it from the code). Remember to add also to uses clause unit VirtualTrees.FMX.

WARNING.

If you install package for FMX you can not use installed package for VCL and vice-versa. I still look for the way to do this.

Virtual-TreeView

Virtual Treeview is a Delphi treeview control built from ground up. Many years of development made it one of the most flexible and advanced tree controls available today. Virtual Treeview starts off with the claim to improve many aspects of existing solutions and introduces some new technologies and principles which were not available before.

Help Needed: Any volunteer that takes care about C++ Builder bugs and packages?

I don't use C++ Builder and my experience with it is very limited. This makes it difficult to take care about bugs that are reported in C++ Builder and to maintain the C++ Builder packages. I would be great if someone would volunteer to do this. Please contact me at joachim.marder+CPP@gmail.com.

Please mark feature requests with the flag "Enhancement".
