Lazarus 1.10.0 is not yet released. This page is under construction!
Statistics:
- commits: xxx
- log: svn log -r xxxx:xxxx
- resolved bug tracker issues: xxx
LCL Interfaces Changes
LCL Changes
- TScrollingWinControl (TForm, TScrollBox, TFrame)
- ScreenToClient and ClientToScreen are now calculated without scrollbar offset. Done for Delphi compatibility.
MouseEntered deprecated/missing
- Old behaviour: No warning on using MouseEntered
- New behaviour: Warning: Symbol "MouseEntered" is deprecated: "use MouseInClient instead"
- Reason: Delphi compatibility
- Remedy: use property MouseInClient instead
IDE Changes
- Delphi Attributes: Find declaration, parameter hints, $modeswitch prefixedattributes.
IDE Interfaces Changes
Components
TOpenGLControl
- New property Options of type set, currently with ocoMacRetinaMode as the only member. If set, ocoMacRetinaMode determines that the OpenGL controls will use retina support (high resolution mode).
TAChart
- The new TExpressionSeries and TExpressionColorMapSeries plot mathematical functions at design-time.
Changes affecting compatibility
LazUtils
LCL incompatibilities
TCustomComboBox.ReadOnly was deprecated
- Old behavior: When True, only items from the list are accepted, by direct selection from the list or AutoComplete.
- New behavior: it does nothing and will be removed.
- Reason: Delphi-compatibility, confusing naming, WS compatibility (different behavior on Win32/Qt/Gtk)
- Remedy: Use extended styles for the same feature.
Predefined clipboard format pcfDelphiBitmap was removed
- Old behavior: The enumeration TPredefineClipboardFormat contained an element pcfDelphiBitmap which once had to be introduced due to streaming differences of bitmaps between Delphi and LCL.
- New behavior: pcfDelphiBitmap has been removed. (Rare) code relying on exact count and position of the elements of this enumeration will fail.
- Reason: No longer needed and causing trouble in clipboard access.
- Remedy: None - revisit your code.
TEdit.Action visibility lowered to public
- Old behaviour: TEdit.Action was published
- New behaviour: TEdit.Action is now public
- Reason: Delphi compatibility
- Remedy: remove from .lfm manually
LazControls
TSpinEditEx no longer inherits from TCustomFloatSpinEditEx
- Old behaviour: TSpinEditEx inherited from TFloatSpinEditEx.
- New behaviour: Both TSpinEditEx and TFloatSpinEditEx now inherit from a common (generic) base class: TSpinEditExBase. As a result testing for "is TCustomFloatSpinEdit" now returns False.
- Reason: support for Int64 values in TSpinEdit (Double does not have enough precision to cover the Int64 range). Also makes for cleaner code.
- Remedy: test for the appropriate (base) class instead.
