Description
the docking demo behaves strangely sometimes, is broken other times, compared to delphi7 version of the docking demo.

tab-sheet host:

using the delphi7 demo, create a floating host with some tabs.  drag a new client over the tabsheets, and you get only one dock-rect allowed - drop the new client and it's added as a new page.  good.

now try with the d2006 demo.  when you drag the new client over, you get additional possibilities for dock-rects: top, bottom, left, right, centre.  all of those do weird stuff.  the new client is not added in a logical way to the others.  instead, the new client and one of the old ones gets combined, and kicked out as a floating pair.

conjoin host:

using delphi7 demo, create the following arrangement of tiles in a floating host:  wide rectangle on top, tall rectangles underneath on the left and on the right:
  AA
  BC
  BC
now dock a new client into the bottom half of rectangle C, to make this arrangement:
  AA
  BC
  BD
works fine.

now try with the D2006 demo.  when dropping D onto C, the host ejects C, and we're left with two floating hosts, one containing A and B, the other containing C and D.

i am very nervous about tapping into the docking provisions of the VCL on account of these differences.  

if i add docking to my app, will i need to rewrite it with each new update of the VCL?
Steps to Reproduce:
1. open ($BDS)\Demos\DelphiWin32\VCLWin32\Docking\dockex.dpr
2. click the "White" toolbutton.
3.  move the "White" window to a convenient location
4.  click the "Blue" toolbutton.
5.  dock the"Blue" window into the Right-hand Half of the white window.
6.  click the "Green" toolbutton
7.  dock the "Green" window into the Right-hand Half of the docked blue window.
8.  click the "Lime" toolbutton
9.  dock the "Lime" window into the Right-hand Half of the docked blue window.

Exp: All four windows will be docked together
Act: The green and lime windows jump out of the other docked group
  (See image attachments 1_xxxx 2_xxxx 3_xxxx)

Note that if the lime window is into either the white or the blue window results are as expected.

Close app and retry with tabbed docking:

1. click the "White" toolbutton.
2.  move the "White" window to a convenient location
3.  click the "Blue" toolbutton.
4.  dock the"Blue" window into the center of the white window to tab-dock.
5.  click the "Green" toolbutton
6.  dock the "Green" window into the center of the tab-docked blue window to add as a tab.

Exp: The green window will be added as a third tab to the group
Act: The blue and green windows jump out of the white window and form their own tabbed duo.
  (See image attachments A_xxxx - D_xxxx)

Tested in RAD Studio 2007 with identical results (using the demo from BDS2006, since I don't see it in the RAD Studio distribution)

I really think you need to add steps to this, not just a description.  Keep each step simple, describing one action (saying exactly how you did it), like:

File | Open | Project | ...Demos\DelphiWin32\VCLWin32\Docking\dockex.bdsproj

F9 or Run | Run

Click on "Red" toolbar button

etc.  Then try following the steps exactly as entered to make sure they do reproduce the problem for you.

After this, someone should have no trouble reproducing the problem unless it depends on some differences in the configuration of the IDE that they use.

hi Leo,

strange but true.  i tried entering in more Steps information, but seemed to reach some kind of limit.  wasn't allowed to type any more characters.  

i thought adding steps sounded easy, but during the process i've ended up filing 3 reports for QC itself, AND i still haven't been able to finish listing my steps information.

Maybe you could continue them at the end of the description.

Aren't the current steps enough?
