VstSearcher

About

VstSearcher - is an advanced search 'engine' for VirtualStringTree (VirtualTreeView) that you can use in your personal projects.

How to use

Note, that you need a RAD Studio IDE with C++0x support (or higher).

Firstly, initialize the searcher by calling the Init() method:

searcher::VstSearcher vstSearcher;
vstSearcher.Init(vtMain, edtSearchStr, lblAmntRows);

Then, specify columns in which you want searcher find matches:

vstSearcher.SearchColumns << 0 << 1 << 2 << 4;

Searcher supports the following options

Option	Description	By default
AUTO_EXPAND_NODES	Automatic expanding nodes where matches are found	YES
RELEVANT_SORT	Apply to the entire list sort by relevance	YES
START_SEARCH_AFTER_BUTTON_CLICK	Start the search after pressing the corresponding button	NO

So you can specify any options you need. For example:

vstSearcher.SearchOptions >> SearchOption::RELEVANT_SORT;

You can also set limits for a search request (by default the min length is 2 and the max 128 symbols):

vstSearcher.SetMinRequestLength(2);
vstSearcher.SetMaxRequestLength(100);
// or
vstSearcher.SetRequestLimits(2, 100);

In order to get rid of the interface freezes on large lists adjust the input delay (default value is 300ms):

vstSearcher.SetInputDelay(1000); // in ms
