changelog

2019-06-10 - version 1.2.1
[*] Trim only trailing spaces when loading text into TextView
[+] New Button property ShadowType = ShadowFull(default), ShadowHalf(bottom

2019-05-10 - version 1.2.0
[*] Dual license: MIT or BSD-2-Clause
[*] Window icons minimize and maximize are swapped
[*] UX improvement: minimize and maximize buttons moved to left side of
    a window to avoid closing window accidentally after misclicking.
    Old window title view:
    ╔Demo═══════[^_X]╗
    New one:
    ╔[_^]═Demo════[X]╗

2019-05-7 - version 1.2.0
[*] Changed default window close icon from "O" to "■"
[*] Doc comments clean up

2019-03-16 - version 1.1.0
[!] TextReader renamed to TextDisplay to avoid confusion with io.Reader. In
    library version 1.x TextReader is deprecated but still available - it is
    just an alias for TextDisplay. In next major release TextReader will be
    removed.
[*] Fix wrong window title for TextDisplay(TextReader) demo

2018-12-01 - version 1.0.0
[*] No changes. No bug reports. The version 1.0 is out

2018-11-09 - version 1.0.0 RC6
[*] If no error is found in the next few weeks, this release will become 1.0.
    It is high time to release 1.0. Everything looks working.
[+] TableView new method VisibleArea - returns first visible column and row,
    and the number of visible columns and rows. It can be useful to prepare
    data beforehand to draw the data faster
[+] Table new event OnBeforeDraw(firstCol, firstRow, colCount, rowCount int).
    The event is fired right before TableView is going to draw itself. So the
    application can prepare all data in one step and then fetch them quickly
    from the cache. The arguments of a callback are the same as returns values
    of VisibleArea method
[+] Added new demo tableview-preload to show how to use new event

2018-10-08 - version 0.9.0 RC5
[*] Fix Frame border drawing

2018-09-30 - version 0.9.0 RC4
[+] New feature: borderless windows (thanks to Mark D Horn)
[+] ScrollTo API for scrollable frame
[*] Clipper fix
[*] ChildAt should skip hidden controls and skip a control if its parent
    is invisible

2018-09-06 - version 0.9.0 RC3 (Thanks to Leandro Dorileo)
[+] New big feature: scrollable Frame
[+] Custom theme support: overriding theme colors with custom ones
[*] Fix bug in getLinearControlList

2018-08-13 - version 0.9.0 RC2
[+] New control: LoginDialog (a dialog with username and password fields)

2018-08-04 - version 0.9.0 RC1
[+] New control: File Picker (a dialog for file save/load operations)
[+] New property for Label: TextDisplay. It defines which part of Label title
   is shown when the title is longer than the Label length:
   - AlignLeft - the head of the Title is displayed
   - AlignRight - the tail of the Title is displayed
[+] New ListBox functions:
   - Item(index int) (title string, ok book) - returns a text of ListBox item
   by its index. If the item does not exist then ok is set to false. The
   function works similar Go 's, ok := map[key]'
   - PartialFind(text string, caseSensitive bool) int - return the index of
   the first item of ListBox that starts with the 'text'. If no item starts
   with the 'text' then '-1' is returned
[*] Fix bug in EditField: when new Title was set the current display offset was
   not reset. It might result in an application crash when new Title was
   shorter than the old one
[*] Fix bug with ListBox 'select item' event: the event was not emitted after
   pressing End, Home, PageUp, and PageDown

2018-07-17 - version 0.8.1
[+] New API functions SetColorMap and GetColorMap to change the current color
    palette
[*] FindNextControl function improved

2018-03-15 - version 0.8.0-RC3
[*] If active control is about to hide then the next control is activated
[*] Setting EditField content with SetTitle moves cursor to the end of line

2018-03-14 - version 0.8.0-RC2
[*] Fixed crash when the last Window is closed from a code call without user
    interaction (e.g, when a Dialog button is pressed the button click handler
    closes the Dialog and the application crashes if the Dialog is the last
    Window in the screen)

2018-03-13 - version 0.8.0-RC1
[+] Added new property for all controls: Visible. It makes possible to show
    and hide any control with its children(if there are any).
    New Control interface methods: Visible and SetVisible
[+] A new event to support hiding/displaying controls: EventLayout with one
    argument - Control that should handle the event. On receiving the event
    the Control must recalculate and reposition all its children.
    At this moment only Windows handle this event. Other kinds of Control
    never receives the event
[+] Add a new simple demo to play with Control visibility: demos/visible

2018-01-26 - version 0.7.0
[+] Added new event handler for Window: set a callback OnScreenResize if you
    want to handle terminal resize event

2018-01-25 - version 0.7.0
[+] Added new methods to Composer: BeginUpdate and EndUpdate to use in
    multithreading application. Call BeginUpdate before creating a new Window or
    manipulating Composer Windows if the code runs in separate thread. And
    call EndUpdate right after all changes are done. Do not lock for a long
    time because while lock is on the screen is not updated.
    Another usage: create new Window inside various handlers (e.g, OnSelectItem
    of ListBox)

2018-01-23 - version 0.7.0
[+] Added feature: Window method to set and read visible buttons in title bar
[+] Added feature: Window manual resizing and moving can be disabled
[*] Fix TableView scrollbars: both scrollbars did not response mouse clicks
    if the last row or column were visible
[*] Fix crash after clicking the first TableView column that shows row numbers
[*] Made function to get internal composer public for low level access to
    function that manipulates Windows. Function name is WindowManager

2018-01-13 - version 0.6.4
[*] Add a workaround for 'false' key presses fired after clicking mouse on OSX

2018-01-02 - version 0.6.3
[+] Add a new boolean property for EditField - PasswordMode. If PasswordMode is
    true then the EditField text is hidden with 'stars'.
    Please see demo demos/editfield for details
[+] Change a theme for object 'Edit' - added non-obligatory forth character
   that is used as replacement for any character inside EditField when Password
   mode is on. By default it is '*' in all included themes. Old themes that
   miss forth character use '*' as well.

2017-12-01 - version 0.6.2
[*] Fix selecting the next control with TAB key

2017-11-28 - version 0.6.2
[*] Fix races (that racy tool shows). The work is not completed but all demos
    and termfb2 application works without warnings

2017-09-07 - version 0.6.2
[*] Setting the first button of confirmation dialog as default one did not work
[*] TableView does not use 'go' to fire events that allows to create on the
    fly any required dialog. That is useful, e.g., to create a simple
    confirmation dialog to a user to approve a row deletion

2017-07-04 - Version 0.6.1
[*] Fix selection Window with mouse: clicking non-active Window makes the
    Window active (unless the top Window is modal one)
[*] TableView does not fire OnSelectionChange event if a user clicked outside
    the table. Before the fix a callback got selected index greater than
    the total number of rows and might crash a callback
[+] Add a new feature to Windows: to keep all changes the Windows can be
    hidden instead of destroying when a user clicks window close button. It
    can be done with overriding OnClose and returning 'true' if Windows must
    be kept. To remove the Window from screen use SetVisible(false)
[*] Window OnClose callback event now must return boolean. See change above
[*] Fix typo: TableView did not send TableDelete event if the selected Row
    was Row number 1

2017-06-30 - Version 0.6.0
[+] Added new control TextReader - a virtual text view control with
    built-in support of some hots keys to list the text
[+] Added a new global event to close active view
[+] Added a hotkey F4 to sort TableView by current column
[+] Added onKeyDown for Window

2016-10-13 - Version 0.5.0

[+] Added mouse move and mouse button release support:
    Now all windows can be dragged and resized with mouse
[+] Added constants for dragging events - new type DragType
[+] Added new type of Event MouseClick: it is generated if a user does mouse
    button down and mouse release at the same coordinates. In this case a
    control receives 3 events: mouse down, mouse release, and mouse click
[+] Main loop moved to separate source file
[+] Added test for color parsing functions

[*] Logger moved to separate source file and it is global object now
[*] Windows do not have their own interface - all objects are derived from the
    same interface
[*] Library initialization is made simpler: only one call is required, there
    is no need to create composer, theme manager etc manually - everything is
    created inside library initialization
[*] Because composer, theme manager and some other objects are hidden now then
    a set of methods are just global library functions:
        - Event processing functions like Stop(), PutEvent() etc
        - Theme manager related functions like SysColor(), SysObject() etc
[*] All functions to create new objects New* are renamed to Create* functions.
    Exclusion: CreateWindow is for internal use only: it creates a window but it
    does not do anything else, so the window is not displayed and a user cannot
    interact with it. Use AddWindow function instead of CreateWindow.
[*] All text output is colorized by default. Multicolor property is removed.
    If you want to draw text as is then use DrawRaw* functions.
[*] Now all drawing function uses the current canvas colors, so all color
    function arguments of all drawing functions are removed. Use global
    functions SetTextColor and SetBackColor to change colors before drawing.
    PopAttributes and PushAttributes may come handy to save/restore canvas
    attributes between drawing calls
[*] Renamed a few constants to get rid of negative constructions:
    DoNotScale -> Fixed
    DoNotChange -> KeepValue

[-] The first argument view of all Create* functions is removed as obsolete.
    Now library does not require to set parent Window. It is sufficient to set
    only control's parent
