Clemens Zeidler ef93b55df4 - Areas with same tabs are put in a column/row automtically. Move preferred size constraint from Area to the column/row. This avoids a "spring" effect of the
quadratic solver if multiple Areas are in the same column/row.
- Replace GetString by ToString.
- some clean up

Clemens Zeidler 7583db5a1e Add an alternative solver to lp_solve. The solver based on Ingo's active set solver but is able to handle arbitrary hard and soft constraints. The advantage to lp_solve is that the active set solver can optimize variable in respect to a quadratic objective function. This makes it possible to minimise the quadratic derivation to a desired value e.g. \Sum_i(x_i - x_{i,pref})^2 -> min.
The solver part has been refactored in this way that both solver can be used with the same layout specifications. The active set solver is default now; the performance is not as good as lp_solve, though.

Clemens Zeidler 8fa4fd37b7 Keep the preferred size ratio into account. This make layout behaviour much more intuitive when resizing a window. Thanks Christof.

Clemens Zeidler b23e9af5b5 Thanks to anevilyak, the previous approach was not thread safe. You can specify a friend layout now if you want to connect tabs of different BALMLayout's.

Clemens Zeidler fc691d7de2 - Remove lp_solve dependencies form Variable class and put everything into LinearSpec. As a side effect Variable management is a bit more consistence now. We want to replace lp_solve soon so it will be easier to replace it just in LinearSpec.
- Update copyrights.
- Lot of small things related to the Variable refactoring.

Clemens Zeidler 37344020ef - Add a alternative method to setup a group layout. BLayoutItem / BView are wrapped into a GroupItem. GroupItem overloads the | (horizontal tiling) and / (vertical tiling) operators. In this manner you can create a group layout using these operators, e.g. GroupItem item = GroupItem(button1) | (GroupItem(button2) / GroupItem(button3)); would layout button1 at the left and button2 and button3 at the right in a vertical layout. All the layout information is stored in the GroupItem item, to setup the final layout you have to call BuildLayout(item). If you like it it could also be added to the BGroupLayout.
- Add operator test app.

Clemens Zeidler 70e2076135 - Add helper functions to get the tabs of a view or a layout item.
- AddView only require the top, left tabs now.
- Remove the TwoViews test and replace it with a slightly more complex test.
- Merge XTab and YTab files into one header file.

Clemens Zeidler 5b6fca0639 - Rework the ALM layout api. The AddItemTo* function are now related to the current Area. On default the current Area is the last added Area.
- Add some more const where appreciated.
- Fix some style issues and a leak in Row and Column.

Clemens Zeidler 19ddd4f1cb SetDefaultBehavior is not needed since all views handled in this function have min and max size equal the pref size (despite of the status bar length, which is ok). As a result they don't grow or shrink undesirable as assumed previously. As a result also the AutoPreferredContentSize is not needed.

Clemens Zeidler 21f083af82 - Implement all Add* function of the BLayout class properly. If the Add* functions of the BLayout class are called add the item to the right upper corner of the previous area. That is at least better than ignore this functions.
- Add more convenience AddViewTo{Right, Left, Top, Bottom} functions to add a item to the sides of an existing area.
- Need to add the Jamfile hack again to include the ViewLayoutItem.h header. I thing about to add the ALMLayout.* files to the interface dir when its a little bit more matured. Then the problem will be solved. Till I made a decision or somebody tell me its a bad idea to add the ALMLayout to the official interface stuff or the ViewLayoutItem.h should be in a shared header dir I will keep this hack.

Clemens Zeidler 40d939a43f - Add some checks if the Area is initialized.
- Init some more variables in the constructor.
- Rename HasSame*As to Set*As. The old one is more a question. Also add an optional factor and remove the HasSameSizeAs function which tempt the user to leak a BList.

Clemens Zeidler 9503cf19be - Don't pass a min size in the Area _Init function. The min size is updated before solving the layout so we don't have to set it in the beginning. This also simplifies the BALMLayout api.
- Header include style fixes.

Also remove LayoutStyle feature because resizing the parent view might not be a good idea. If the parent view should be resized you should better but it into a BLayout too.

Alex Wilson 1d6c7b6cb6 Big change deriving BLayout from BLayoutItem, and allowing viewless BLayouts.
a few highlights:
* BLayout now derives publicly from BLayoutItem
* Added BAbstractLayout class, which our layouts now derive from
* updated layout builders to avoid creating views when they don't need to
* updated layout classes
* updated AboutSystem to fix a little regression
* more details on #6407
* please tell me about any regressions, I've tried to find them all, but some
  may have slipped by.

Ingo Weinhold 5bced18eab ALM/linprog patch by Christof Lutteroth:
* Got rid of class ObjFunctionSummand. Both the constraint summands and
  the objective function summands are now stored using class Summand.
* Some method names are more BeOS compliant now: SetX instead of ChangeX.
* linprog test code now uses new AddConstraint methods.
* CalculateMinSize and CalculateMaxSize did not free the memory they
  allocated.
* Removed inappropriate setter and getter methods.
* Memory allocated in class Constraint is freed now.
* Other small changes.

  supports both soft and hard constraint functionality
* new AddConstraint methods in class LinearSpec for directly setting
  constraints with 1 to 4 summands
* code cleanups by using aforementioned AddConstraint methods
* a new very simple test application for alm
* some style corrections

Ingo Weinhold a101e99aad Added libalm.so and its dependency liblinprog.so. libalm.so provides a
BLayout implementation (BALMLayout) using the Auckland Layout Model
(ALM). The original ALM was implemented by Christof Lutteroth, the
Haiku/C++ version by James Kim.
The code needs some review, but the test programs seem to work fine.
