v1.8.4 [Jun 19, 2017]
LCL Interfaces Changes
• Qt5: new widgetset based on Qt5 libraries.
LCL Changes
• TApplication
o Scaled property: the LCL is DPI-aware. Please see High DPI for more information.
• TCustomForm
o new position poWorkAreaCenter - center form on working area (depends on DefaultMonitor)
o new compiler define LCLRealFormBounds. If you compile your application with LCLRealFormBounds on, the TCustomForm bounds (Width/Height) will be real outer bounds and not client bounds. Also constraints will affect real bounds. For now, it is supported only by win32.
o Scaled property: the LCL is DPI-aware. Please see High DPI for more information.
• TToolButton
o new style tbsButtonDrop - paints a drop down arrow on the right side of the button. In contrast to tbsDropDown the button has only single clicking area that invokes the DropDownMenu if assigned.
o new event OnArrowClick. It is called if Style=tbsDropDown when the user clicks the arrow button area of toolbutton. Breaking change: In 1.6. the OnClick event was called for this!
• TToolBar
o new DropDownWidth property to setup the width of the toolbutton arrow area for Style=tbsDropDown.
• ClipBoard
o The ClipBoard now supports copying and pasting text in HTML format by means of the methods GetAsHtml and SetAsHtml.
• Menus (TPopupMenu, TMainMenu, TMenuItem)
o Menus now support OwnerDraw with (almost) Delphi's approach. If you set TMenu.OwnerDraw to true the OnMeasureItem and OnDrawItem from TMenu and TMenuItem will be called. OnDrawItem from Lazarus has the same parameters as OnAdvancedDrawItem from Delphi. You can use the events also from TMenu, which is an LCL addition to Delphi. For now only win32 is supported.
• Dialogs
o TTaskDialog added
• TDateTimePicker
o new TDateTimePicker.Options property
IDE Changes
• lazbuild
o new option --add-package-link to register given lpk files without building.
• Quick Fixes
o new QuickFix for any fpc hint, note or warning: add compiler directive {$warn id off}
• Code creation
o new shortcut Ctrl ⇧ Shift X that shows a CodeCreation dialog with more options. Ctrl ⇧ Shift C never shows a dialog now.
o You can choose the default visibility of the methods in Tools / Options / Codetools / Class Completion / Default section of methods.
• Word Identifier completion: If the option Codetools / Identifier Completion / Replace whole words is enabled, pressing Return replaces the whole word at cursor, pressing Shift Return replaces only the left side. If the option is disabled it works the other way round: Return replaces left side, Shift Return replaces whole word.
• "case ofall" code template indentation change
o Old behavior: the created case-list was always flat
o New behavior: by default it is now indented according to source editor options.
o Reason: the indented case-list is Delphi-standard
o Remedy: edit the ofall template and use the WithoutExtraIndent parameter: "$OfAll(WithoutExtraIndent)"
• Ctrl-Enter alias "Open file at cursor" was improved when cursor in a Pascal file: It now recognizes properly $I and $R directives, uses nodes, string literals and comments.
• DPI awareness: the IDE is DPI-aware (it's ongoing work, so expect issues). Please see High DPI for more information.
• pas2js support:
o parsing the external class declaration of pas2js, code completion, find declaration, etc.
o namespaces: The IDE supports the -NS option and project default name spaces of Delphi/pas2js. As soon as FPC supports namespaces Lazarus supports it too.
• Editor
o New colored outline of source structure. (like cnpack, if then block outline)
• Support for Win98/WinNT has been dropped.
IDE Interfaces Changes
• New function LazarusIDE.FindUnitsOfOwner listing all units of a project/package. [1]
Components
LazControls
• Added T(Float)SpinEditEx, a widgetset independant implementation of T(Float)SpinEdit with some extended capabilities:
o NullValue property.
o Configurable behaviour when the text inside the control is not a number.
ToDoListLaz
• Now searches all used units of projects. Excluding used packages, including all units listed in the project inspector.
TAChart
• New component TChartCombobox
• Improved data point tools (property Target)
• New demos (runtime demos, datapointtools)
EditorToolbar
• The package editortoolbar.lpk is removed and its functionality is integrated in IDE.
o The settings can be found in Tools -> Options -> Environment -> Editor Toolbar

v1.6.4 [Dec 23, 2015]
- Added TFlowPanel in ExtCtrls.pp
- The TreeNodes of TShellTreeView are now of type TShellTreeNode. In order to access the nodes as such, you need to explicitely cast the node to TShellTreeNode. The TShellTreeNode class provides the following functions and properties:
- ShortFilename: returns the filename without path.
- FullFilename: returns the fully qualified filename.
- IsDirectory: returns True if the node represents a directory.
- BasePath: returns the basepath of the node.
- Added 'iscancel' parameter to QuestionDlg. If no cancel button is explicitely set, mrCancel is returned in case the dialog is closed with ESC or system close button.
- Added support for TCustomEdit.TextHint.
- Added TTimeEdit in editbtn.pas.
Editor
- Basic multi-caret mode
- Option for multi-line notebook-tabs
- line-number part of gutter now allows to select the current line, or several lines.
Project
- Additions and Overrides are now added as last. Formerly they were added after the inherited and before the custom compiler options.
Messages Window
- The IDE now warns when there are duplicate units or include files in packages.
- Success line. New option to show compiler message "n lines compiled. m sec". Tools / Options / Messages Window / Show FPC message "lines compiled"
Desktops
- See Desktops
- Multi-monitor screen layouts are supported by the IDE.
IDE CoolBar and Editor Toolbar
- A new configurable IDE CoolBar replaces the static Toolbar. It shares settings GUI with EditorToolbar which was moved to IDE's codebase. The command set that can be selected was refined. Earlier only IDEMenuCommands could be selected, now a limited selection of all IDECommands.
- EditorToolbar package is empty and deprecated. It's functionality is now part of the IDE. Please uninstall it from the IDE because it will be removed from the 1.8 release.
Object Inspector
- The Boolean property editor now uses a CheckBox by default. A ComboBox with "False", "True" can still be selected in options.
Package editor
- Two separate buttons for adding files were replaced by one button with a dropdown menu. The "Add" and "Add more" buttons can be considered a failed experiment.
- Many usability issues were fixed. The whole tree is not updated any more after each operation and focus stays in right place after them.
Environment
- new Environment setting "Multiple Lazarus instances" to set up what happens if Lazarus is started with a file in command parameter.
lazbuild
- new option --verbose-pkgsearch to show what packages are searched and found.
lazarus
- new option --force-new-instance to force opening a new instance and ignoring the "Multiple Lazarus instances" option.
- Code navigation and completion for class helpers, record helpers and type helpers.
