# ef93b55d 13-Mar-2011 Clemens Zeidler <clemens.zeidler@googlemail.com>

- 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

# 7583db5a 24-Jan-2011 Clemens Zeidler <clemens.zeidler@googlemail.com>

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.

# f108cdbf 13-Dec-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

Merge all linear programming types in one file an rename them.

# 5440f6fe 13-Dec-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

Refactor the linear programming class to use a minimal solver interface class and implement the interface for lp_solve. As a result lp_solve is not visible to the outside any more. This interface could be used to use other solvers as well. Rename operator constants to no clash with lp_solve constants.

# 8fa4fd37 25-Nov-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

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

# b23e9af5 21-Oct-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

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.

# 56187df6 21-Oct-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

Use a global solver per application. This make it possible to wire different BALMLayout's.

# c2f0a314 12-Oct-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

Rename ReplaceObjectiveFunction to SwapObjectiveFunction I think this makes it more clear that the old function is not deleted.
Cleanup Jamfile.

# fc691d7d 05-Oct-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

- 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.

# 37344020 03-Oct-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

- 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.

# 70e20761 29-Sep-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

- 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.

# 5b6fca06 28-Sep-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

- 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.

# 19ddd4f1 23-Sep-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

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.

# 21f083af 23-Sep-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

- 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.

# 96e2013e 22-Sep-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

Add inset and spacing to BALMLayout. Each Area is able to overwrite this global values and use his own inset. Add spacing and inset to the tests.

# 9503cf19 22-Sep-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

- 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.

# 0871de7b 21-Sep-2010 Clemens Zeidler <clemens.zeidler@googlemail.com>

Remove unsupported reverse engineering feature. Further clean up.
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.

- 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

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.

Refactor the linear programming class to use a minimal solver interface class and implement the interface for lp_solve. As a result lp_solve is not visible to the outside any more. This interface could be used to use other solvers as well. Rename operator constants to no clash with lp_solve constants.

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.

- 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.

- 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.

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.

- 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.

- 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.
