<div>
I forgot to change the declaration of TabStop property default value (which is advisable if you set your defaults in the constructor differently than the ancestor does):<br />
<br />
type<br />
&nbsp; TTestControl = class(TCustomControl)<br />
&nbsp; ...<br />
&nbsp; &nbsp; property TabStop default True;<br />
&nbsp; end;
</div>

Thanks! I handled every single message from WM_SETFOCUS to WM_DIALOGCHAR but it never occured to me to catch CM_ENTER and EXIT. :)<br />

Hi,<br />
<br />
I have a problem with a set of visual components I'm developing. I'm sure it's something basic, but I'm pretty new to component design so please humor me if I'm asking something really stupid.<br />
<br />
My controls are all descendants of TCustomControl and for the most part they work perfectly, with one little exception. They don't receive focus when I press the TAB key. The TabStop value is true, everything (as far as I know) is set up correctly but still, they just don't receive focus with the TAB key. (Clicking on them with the mouse does work, of course.)<br />
<br />
Please help.<br />
