# Change History 在某些情況下，4.25版本修復錯誤會阻止在Windows上執行。 4.24版本包含對小部件圖像和字體規范的進一步更正。 它還有助于使用多個初始化文件。 請參閱[初始化和執行PAGE](intro.md) 4.23a版本修復了阻止代碼生成的錯誤。 4.23版本修復了多個錯誤，一個錯誤與Scrolledtreeview有關，另一個錯誤與在沒有IDE規范的情況下生成代碼有關，另一個與在“屬性編輯器”中更改相對大小屬性有關。 此外，圖像使用的某些方面已得到改進。 字體支持顯示錯誤，必須進行修復。 最后，解決了編碼問題和國際化問題。 4.22版本修復了多個錯誤。 4.21版本包括很多支持的小部件和錯誤修復的氣球幫助（工具提示）。 4.20版本修復了與Scale小部件和Scrolledtreeview小部件有關的錯誤。 4.19版本： * 提供存儲和應用機制，用于將屬性從一個小部件轉移到另一個小部件， * 啟用“屬性編輯器”中的上下文菜單，以將屬性從一個小部件轉移到其他小部件-[請參閱屬性編輯器](interface.md), * 進一步增強了PAGE窗口的滾動， * 修復了一些錯誤，其中一些錯誤與顏色偏好有關， 4.18版本： * 增強了“滾動”小部件，以支持鼠標滾輪在生成的Python模塊中的數據窗口上滾動， * 增強了鼠標滾輪在PAGE數據窗口上的滾動， * 刪除了一些警告消息并添加了其他更有意義的消息， * 改進了tkinter導入語句的樣式（請參閱[命名約定](use.md), * 將行號添加到Python控制臺， * 將頂部按鈕添加到多個PAGE窗口中，… 4.17版本：在“屬性編輯器”中顯示窗口小部件的鎖定狀態，添加用于設置縮進的首選項，在更新支持模塊時展開選項卡，修復在標架窗口小部件中放置的細微錯誤，并增強了幾何屬性在 屬性編輯器。 4.16版本修復了支持模塊更新功能中的一個重要錯誤，并改進了“填充容器”功能。 4.15版本改進了綁定窗口的使用，改進了回調函數的顯示以及自動保存了項目文件。 添加了ttk :: separator小部件，并擴展了對自定義小部件的支持。 現在可以鎖定各個小部件的幾何形狀，以防止更改鼠標。 4.14版本提供了將小部件樹保存到文件的功能以及顯示回調函數的功能。 還針對復制和粘貼以及相對位置進行了修復。 The 4.13 release adds a search function to the Python Consols, fixes a syntax coloring problem, adds additional support for utf-8 encoding, and fixes some bugs. The 4.12 release fixes several bugs related to placement, cut and paste, and borrowing. The 4.11 release allows one to copy a menu bar from an existing project to the current project. An important addition is the inclusion of a tutorial written by Greg Walters. The 4.10 release includes a reuse facility which allows one to copy from existing projects and paste to the current project. This release also modifies the startup to automatically create the Toplevel widget and expands support for the Canvas widget and adds some checking of identifier syntax. In addition, there is a new custom version of the TNotebook widget which incorporates an icon for closing tabs. The 4.9 release fixes bugs related to state values of several widgets. It also improves the Widget Tree by changing the labels to display the class and the alias of the widget and automatically updating it in more cases. The 4.8.x releases fixes bugs and updates the documentation. The 4.8 release includes support for Custom widgets which are widgets for which the Python implementation is left to the user. Python 3 versions of the examples are included. The widgets handles have been enlarged and colored to facilitate selection. Bugs related to the changing of aliases have been corrected. Finally, a function which expands a widget to fill its container has been added to some widgets I have fixed some bug within the font handling code and that may require that fonts in existing PAGE projects be re-specified. The 4.7 release includes support for binding events to top level windows and reorganizes the generated code for greater clarity and provides variable parameter lists for the init function in the support module using the Python convention of \*vargs, \*\*kwargs. Important fixes for Cut, Copy, and Paste and for the TCombobox widget. The 4.6 release includes new function. a) Shows generated code in separate console windows. b) Allows loading of consol windows without generating code. c) Allows the opening of user’s favorite IDE with saved versions of the generated code. d) Corresponding changes in the Gen\_Python menu. The 4.5 release incorporates new flexibility for the location of the toplevel widget in the generated GUI using the default location determined by the window manager. The 4.4.x releases contain bug fixes. The 4.4 releases supported popup or context menus. Also, support for ttk menubuttons was removed pending more debugging and the Labelframe widget was added. Finally, support for function definition was; however, PAGE still defined skeleton functions as before. The 4.3 release includes code to update an existing support module with Tkinter variables and skeleton functions newly required as a result of [Rework](file:///C:/Program%20Files/page/docs/html/rework.html#rework). The 4.2 releases has new function which aids [Rework](file:///C:/Program%20Files/page/docs/html/rework.html#rework). This is a fairly extensive departure from the previous workings of PAGE. Additional examples were added to illustrate some aspects of the rework scheme. They also provided additional Help and additional scrolled widgets. The 4.1 releases contains several changes dealing with preferences dealing with font preferences and function to backup versions of the generated GUI. The 4.0 release contains sufficient advances including: > * Significant improvements in the specification and clarity of Preferences. > * Significant work with color and associated connections with styles. Emphasis on readability of generated style code. Unfortunately, this seems to work better with Linux/Unix systems than with Windows or OS X. > * Better support for OS X. > * Better support for the Scale and TScale widgets. > * Better support for Toplevel widgets. You can now change attributes; background and cursor, for example. > * Corrected problems with the TMenubutton. > * Shifted emphasis to Python 2.7 from 2.6. > * Added the ttk::sizegrip widget. > * Fixed numerous bugs. The 3.0 release was a major revision of PAGE initiated because of the following events: > * The release of Tcl/Tk 8.5 which includes the ttk widget set. This is a themed widget set containing new core widgets such as notebook, combobox, treeview and progressbar widgets. Further, the themed feature allows the same design look natural on Linux, Windows, and OS X. > * The advent of a new version of Visual Tcl upon which PAGE is built. The new version provides an improved user interface. > * I have realized that some of the bells and whistles that I included before are superfluous or perhaps error prone. > * Although relative placement was incorporated in the previous version, it added to the desirability of making a major revision because some Tix widgets had some problems when stretched. I want to thank George Tellalov for his suggestions and encouragement regarding this feature. > * The Pyttk package by Guilherme Polo showed me how to create scrolled versions of text boxes and list boxes in a very transparent manner.
