<p style="padding:0 0 0 0; margin:0 0 0 0;">It wouldn't be that hard to write custom component based on TGraphicControl + TBitmap with built-in bitmap font. Copying bitmap letters will be faster than rendering from ttf.</p>

<br />
Now I wonder if there is some way to do as I did when I worked in Delphi with<br />
TListView objects, where I could use the BeginUpdate and EndUpdate calls to make<br />
all screen updates wait until it was all put in place.<br />
This was MUCH faster!<br />
<br />
But I can not find a BeginUpdate on the TListBox object, only BeginUpdateBounds,<br />
which does not tell me much....<br />
<br />
Any suggestions?<br />
<br />
