It seems some
components (VT, ListView etc) don't really know what they want to be. <span style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); display: inline-block; overflow: hidden; height: 18px; width: 18px; text-indent: 18px; vertical-align: middle; " class="u-smiley u-smiley--wink">;-)</span><br></pre></blockquote><div> <br></div>
<div>Both, As VTV is the best grid-ish component I fount in Lazarus world. Kgrid is good but slow.<br></div>

equivalents, so you don't need 3rd party component suites. eg: fpGUI's
standard TreeView and StringGrid are really fast. For example the last
time I testing fpGUI's StringGrid it could create 8 million columns and
rows and populate each cell with unique text in 5 seconds. Scrolling was
instant with no delays. LCL's TStringGrid got stuck at 100% CPU load for
over 3 hours before I killed the process.<br></pre></blockquote><div id="sig12586409"><div class="signature"> <br></div>
<div class="signature"> You are right about LCL speed, it's grids are for simple use and I never used them in a real project but in the other hand VTV is the fastest I found and has many abilities (not built in unfortunately ) as editors and ... .<br></div>
<div class="signature">I didnt see a grid for this usage in fpGUI demos at least in my last check. Can it be a good grid because I miss DevExpress's cxGrid very much and I dont expect its abilities but I need VTV abilities at least.<br></div>
