[Lazarus] StringGrid.Options: goSmoothScroll vs goThumbTracking
Hi, Could anybody explain to me what the difference is? I noticed that if I enabled both options I get the desired effect. Smooth scrolling and seeing all content scroll by as I move the scrollbar. But what do they do on there own? goSmoothScroll - I first thought this is what I wanted as described above, but on it's own it don't do that. goThumbTracking - isn't this supposed to be the same as goSmoothScroll, compared to jumping columns or rows at a time. There is no LCL reference help describing the available settings in TStringGrid.Options property. http://lazarus-ccr.sourceforge.net/docs/lcl/grids/tgridoptions.html Regards, - Graeme - ___ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

OK, I think I figured it out. goSmoothScrolling - scrolls pixels at a time, not columns/rows. goThumbTracking - gives you a like preview of the contents as you move the scrollbar. Now isn't it a bit pointless having goSmoothScrolling enabled, but goThumbTracking disabled by default? The content might scroll per pixel, but you don't see any content updating until _after_ you release the scrollbar thumb button. I would think the more logical default would be to have both there options enabled by default. I'm using 0.9.26 and they are not both enabled by default. PS: If my description of these options are correct, I'll update the Grid docs and send a patch.

Has Delphi goThumbTracking and what is it the default value there? Yes, and it's not a default option in .Options property. Saying that, Delphi doesn't have goSmoothScrolling option. I only have Delphi 7. Either way, with the available options in Lazarus (and some not being available in Delphi), I still think it's more logical to enable both options as I suggested. With the current default values, goSmoothScrolling makes no sense and has no affect.

I would think the more logical default would be to have both there options enabled by default. I'm using 0.9.26 and they are not both enabled by default. AFAIR that's the Delphi default, suitable for slow systems. Thumb tracking was available for the original Windows controls. Smooth scrolling came later, when the typical systems had more processing power. Smooth scrolling IMO should be disregarded when the scroll distance becomes larger than one page, or when it's known that the user dragged the slider.

* Packages | Open package file (*.lpk)

* select sqldblaz.lpk
* In the new dialog, click Compile

* Lazarus should now restart and you should see the SqlDB tab.
That worked a treat. Many thanks, Graeme.
Just as an FYI:
The above method installed the updated Lazarus under my home directory.
To make the SQLdb tab universally accessible, one can build (as root)
the main Lazarus program using:
cd /usr/share/lazarus
make clean bigide LCL_PLATFORM=gtk2 {or qt, or whatever}
This will also make the RTTI and IPro tools available.
It would be nice if this were documented in the README.txt file that is
included in the Lazarus bundle.

Dmitry, Thanks for rapid fix. But I am not accustomed to building Lazarus as a n application bundle (I used to get pre-built binaries from the snapshots). P lease allow me a few days of trial.
