Core Library

  • fixed possible crash when an object has beed saved with a different name than proposed
  • Field draging: API improved, now both query and table fields/columns can be dragged; added support for multiple fields dragging
  • added 'higlight object' action for KexiProject(external) (available from property pane)
  • improved API for reaction on object creation/deletion/renaming
  • applications/x-kexi-connectiondata MIME type defined
  • internal BLOB storage framework added
  • Fixed autogenerating object names (e.g. tables, queries) based on caption: latin1 base name can be now chosen by translator
  • Plugins: added servicetype property: X-Kexi-SupportsDataExport (boolean); true for tables and queries
  • file dialog's filters now contain only filters that make sense, e.g. there's no "mdb" filter when we're writing to a file.
  • usability: file dialogs now store recent directory paths in the config file, and this is now used everywhere in Kexi
  • default extension is properly added when there's multiple filters set in the file dialog
  • custom "Identifier" property type and editor added (allows only entering identifiers); used in Table/Form/Report Designers
  • possibility of adding non-db-aware windows/tabs in Kexi
^ toc

Plugins ^ toc

Table Designer

  • fix for 'subType' combo box
  • avoid possible infinite recursion
  • selecting non-integer type group using 'type combo' clears PKEY flag, if set
  • fixed retrieving field captions and descriptions
  • Field captions can be now entered by users instead of names. Field names are then automatically generated.
  • fixed problem with undo button for subtype combo box
  • avoid asking twice for saving changes to the design on window closing
  • find unique name for autogenerated primary key fields
^ toc

Query Designer

  • a few bugs for relationships creation fixed
  • object combo box now also contain queries (supporting queries is not implemented yet though) the list within the combo is property sorted and grouped; it's reused in 'Data source' tab of the Property Pane; the combo now reacts on deleting/creating/renaming of table or query
  • fixed redrawing (in an unoptimized way)
  • conditions: ambiguous expressions fixed: " > 100" is used instead of "id > 100" in queries like SELECT * FROM t1, t2 WHERE = AND > 100
  • fixed possible crash when invalid query design is loaded in design view
  • fixed switching to design mode after invalid query was opened directly in text mode
  • eat parentheses on criteria loading, in WHERE conditions like ( = value)
  • also accept tableName.fieldName on criteria loading, not only tableName
  • also accept e.g. "2 = variable" as condition, not only "variable = 2"
  • graphical representation of joins is generated back from SQL statement, not only based on explicit query schema's relations but are also retrieved from "t1.f1 = t2.f2" expressions within WHERE section
  • fixed displaying criteria for table view rows when 'visible' column is set to false
  • all-tables-asterisk is also hidden when last table is hidden
  • fixed possible crash when switching back from SQL View to Design View
  • fixed displaying criteria if WHERE section contains '('
  • tables' positions are preserved if possible when relations view updating is needed
^ toc

Form Designer

  • "vAlign" property is now invisible for lineedit widgets (it's noop there)
  • "(autonumber)" label is (identical to the one in tableview) is displayed in lineedit and label widgets assigned to autonumbered fields
  • shadow in label widgets is properly set for altered indenting, margins and alignment
  • double focusing of text field fixed
  • "format_font" action added; it's now possible setting font for one or multiple widget's standard using font dialog
  • fixed crash when there're missing widgets
  • record is properly fetched on subsequent switching to Data View mode, specially after data source changes
  • data aware 'text editor' widget added
  • we're not creating additional (blue) resize handle set, but just change color of existing set thus resizing works well even if we're during inline editing
  • copy common properties from an editing widget to an inline editor (e.g. "margin")
  • fixed resetting cursor after editing
  • on creating a new spring, splitter and line widget, orientation is set according to its aspect ratio; if the ratio is undefined, popup menu with vertical/horizontal/cancel options is displayed
  • fixed crash when pressing Tab key on form surface in design mode
  • Data source tab in the Property Pane implemented
  • fixed switching property buffers when switching between child windows
  • record navigator is now hidden if there's no data source assigned for a form
  • fixed i18n for property captions
  • fixed filling enum values
  • better handling multiple widget selection; fixes for widget info label
  • data source fields can be dragged from Data Source Pane and dropped on the form's surface to create data-aware line edit widgets
  • on new form empty creation, undo/redo history is cleared and undo/redo actions are not available
  • on design time, 'dataSource' properties for forms and dataaware widgets are synced with data source combo boxes
  • inline editing enabled for checkbox widget
  • width of inserted widgets' size hint increased a bit to for better usability
  • better support for Auto Fields, including drag&drop
  • editor inside Auto Field is visible at design time
  • version information is loaded/saved within form's UI string
  • field editor's default focus policy is now inherited from internal editor
  • autocaption is set properly for field editor on design time
  • field editor's labelCaption is no longer needed
  • avoid adding accelerators
  • properties like "iconText" are properly hidden
  • when a widget is deleted or cut, its parent container become selected
  • added possibility of inserting autofields using 'Insert fields' button from Data Source tab
  • make a single command out of 'inserting multiple autoFields' task
  • top-level form surface is resized when inserted autoField(s) couldn't fit
  • inserting autofields is atomic command supporting undo/redo
  • "other widgets" toolbar popup added for clarity
  • data-aware image box widget": "insertFromFile", "saveAs", "cut", "copy", "paste", "delete", "properties" popup actions added
  • "readOnly" property added for image, spinboxes and dbfield widgets
  • widget's look&feel can differ depending on the view mode
  • support for static and data-aware images boxes; properties implemented: scaling (aspect ration can be kept), horizontal/vertical alignment
  • Images are stored in memory in original form, converting to QPixmap is only performed for displayoing purposes. Such original pixmap can be saved back to file. Original file name is also kept.
  • Application-wide buffer for local (static) BLOB data like pixmaps. For now only pixmaps are supported. Used on design time before objects are stored. This allows to copy multimegabyte pixmaps within Kexi without unnecessary memory loss.
  • handle Kexi-specific property editor items
  • accessibility: allow changing the tab order of widgets in the Edit Tab Order dialog using keyboard
  • AutoField widget: update label for font/palette change, display "Unbounded Auto Field" text when no data source is set (in design time, like for image box); improved behaviour in design time (setting caption/type/label position)
  • "frameColor" property added for widgets like text label or frame: behaves well also for "raised" frame shapes
  • new frame widget "KexiFrame", will provide more features; backward compatible with QFrame
  • do not allow to move top-level widget's position using arrow keys
  • memory for data is now properly freed before closing a form
  • infinite loop removed when updating multiple selection
  • "Assign Action" dialog cleaned
  • versioning added for widget library plugins; this can also avoid conflicts between plugins as we've just renamed them
  • Data source pane: disable widget's data source combo box when there is no form's data source is defined

^ toc

Main Window

  • 'close all' works well if there are more than one yes/no/cancel dialogs required to show
  • missing icons added: small icons cleaned up; added better query/form/report/script icons
  • crash fixed in 'detach window' action (Childframe mode)

^ toc

KexiDB (Database Support Library)

  • field names converted to lowercase in memory to avoid problems with comparisons
  • TableOrQuerySchema helper class added
  • Database Properties utility class added to API
  • More verbose error messages: Error messages and result numbers can be now inherited, so less information will be lost while displaying message e.g. on failed cursor opening.

  • Files like MS Access .mdb can be clicked and then Import Wizard will pop up with preselected parameters. This also works using the command line options.
  • check for existence of a file user has selected to open
  • added --print and --print-preview command line options
  • Project Migration Wizard is proposed if a server-based database is incompatible with Kexi and cannot be opened
  • "--skip-dialog" command line option added. Skips displaying connection dialog and connects directly. Available when opening .kexic or .kexis shortcut files.
  • opening server-based projects works in File->Open when there's already project opened.
  • "--connection <shortcut_filename>" command line option added. Specifies a database connection shortcut .kexic file containing connection data. Can be used with --createdb or --create-opendb for convenience instead of using options like --user, --host or --port. Note: Options like --user, --host have precedence over settings defined in the shortcut file.
  • creating server-based projects works in File->New when there's already project opened.
^ toc

MS Windows-Specific
