bBrowser 4 Version-History

4.4

Improvements

• bBrowser and cell group resize
  If the size of a cell group is changed with the mouse, the size of the cell group is limited to the right or bottom margin.

Bug Fixes

• bBrowser and move cell groups vertically
  The vertical moving of cell groups was only supported if both the option BCGIO_MOVABLE_VERTICAL and BCGIO_MOVABLE_HORIZONTAL was defined in the access bCellGroupItem:Options. If only the option BCGIO_MOVABLE_VERTICAL was set, then vertical moving was not supported. This problem has now been solved.
  
  
• bBrowser and move cell groups
  If a cell group was moved to the right margin of another cell group, the moved cell group was incorrectly subordinated to the other cell group as a child element. This problem is now solved.
  
  
• bBrowser and cell groups
  Fixes an error when drawing cell groups if they were below the column captions. It could happen that the cell groups overlapped the column captions.
  
  
• bBrowser and alternate background colors for record groups
  Fixes an error with alternating background colors in connection with group headers for record groups.
  
  
• bBrowser:Refresh()

Improvements

• bBrowser and default font
  If none font is defined in the bBrowser then the Windows font ANSI_VAR_FONT is no more used but the Windows font DEFAULT_GUI_FONT. This font contains more special characters than the other one.

Bug Fixes

• bBrowser and multiple selection with record groups
  The methods bBrowser:SelectionFirstRow() and bBrowser:SelectionNextRow() did not consider closed record groups. This was the reason that selected records in closed record groups were skipped. Only the first record of a closed record group was returned. This problem is fixed now.
