wxPython – Major Classes
WxWidgets gốc (viết bằng C++) là một thư viện lớp lớn. Các lớp GUI từ thư viện này được chuyển sang Python bằng mô-đun wxPython, mô-đun này cố gắng phản ánh thư viện wxWidgets gốc càng giống càng tốt. Vì vậy, lớp wx.Frame trong wxPython hoạt động theo cùng một cách như lớp wxFrame trong phiên bản C++ của nó.
wxObject là cơ sở cho hầu hết các lớp. Một đối tượng của wxApp (wx.App trong wxPython) biểu diễn chính ứng dụng. Sau khi tạo GUI, ứng dụng sẽ đi vào vòng lặp sự kiện bằng phương thức MainLoop(). Các sơ đồ sau mô tả hệ thống phân cấp lớp của các lớp GUI được sử dụng phổ biến nhất có trong wxPython.
| S.N. | Classes & Description |
|---|---|
| 1 | wx.Frame Class has a default constructor with no arguments. |
| 2 | wx.Panel class is usually put inside a wxFrame object. This class is also inherited from wxWindow class. |
| 3 | wx.StaticText class object presents a control holding such read-only text. It can be termed as a passive control since it doesn’t produce any event. |
| 4 | In wxPython, an object of wx.TextCtrl class serves this purpose. It is a control in which the text can be displayed and edited. |
| 5 | Each button, an object of wx.RadioButton class carries a text label next to a round button. wxPython API also consists of wx.RadioBox class. Its object offers a border and label to the group. |
| 6 | A checkbox displays a small labeled rectangular box. When clicked, a checkmark appears inside the rectangle to indicate that a choice is made. |
| 7 | A wx.ComboBox object presents a list of items to select from. It can be configured to be a dropdown list or with permanent display. wxPython API contains a wx.Choice class, whose object is also a dropdown list, which is permanently read-only. |
| 8 | Wx.Gauge class object shows a vertical or horizontal bar, which graphically shows incrementing quantity. |
| 9 | wxPython API contains wx.Slider class. It offers same functionality as that of Scrollbar. Slider offers a convenient way to handle dragging the handle by slider specific wx.EVT_SLIDER event binder. |
| 10 | A horizontal bar just below the title bar of a top level window is reserved to display a series of menus. It is an object of wx.MenuBar class in wxPython API. |
| 11 | If the style parameter of wx.Toolbar object is set to wx.TB_DOCKABLE, it becomes dockable. A floating toolbar can also be constructed using wxPython’s AUIToolBar class. |
| 12 | Although a Dialog class object appears like a Frame, it is normally used as a pop-up window on top of a parent frame. The objective of a Dialog is to collect some data from the user and send it to the parent frame. |
| 13 | wx.Notebook widget presents a tabbed control. One Notebook object in a frame has one or more tabs (called Pages), each of them having a panel showing the layout of controls. |
| 14 | Object of this class is a layout manager, which holds two subwindows whose size can be changed dynamically by dragging the boundaries between them. The Splitter control gives a handle that can be dragged to resize the controls. |
| 15 | wxHTML library contains classes for parsing and displaying HTML content. Although this is not intended to be a full-featured browser, wx.HtmlWindow object is a generic HTML viewer. |
| 16 | A wx.ListBox widget presents a vertically scrollable list of strings. By default, a single item in the list is selectable. ListCtrl widget is a highly enhanced list display and selection tool. List of more than one column can be displayed in Report view, List view or Icon view. |
