Major refactoring of the runtime code, Specifically:
- Move the bulk of the core code from main() into a new Runtime class.
- Break up the mass of code that was main() into a number of relatively simple functions.
- Make the Configuration dialog synchronous so the Log dialog can be properly viewed.
- Enable/disable menu options at the right time.
- Remove support for Qt < 5.0.
- Remove the application name constant and hardcode the name to simplify the code.
- Improve log messages.
- Replace the sdbm hashing with Qt's MD5 hashing.
1) Shutdown the python server properly.
2) Disabled "Shutdown server" menu till server is not successfully started.
Initial patch sent by Maxim, modified by Akshay Joshi.
Added functionality to open different website link and load the
website data to different tab. To achieve this, new customized
QTabWidget and QWebView are added to render the data to WebView
widget. All the widgets (New Tab, WebViewWinodw, and QToolButton)
are added dynamically. QToolButton is used to traverse back and
forward to web document opened in WebViewWindow.
Introduced the New class called WebViewWindow which is derived
from QWebView. Each tab of the QTabWidget contains the instance
of WebViewWindow class. WebViewWindow class is useful to display
the web document.
Introduced New class called TabWindow which is derived from
QTabWidget. This class is useful to achieve following functionality:
- Customize the close button of tabbar so that it can only be
visible other then main pgAdmin 4 window.
- Enable/Disable the toolbutton added left side of tabbar
depending on the web history traversed by the user in WebViewWindow.
- Set the tooltip text of the tabbar depending on the title change
event of WebViewWindow class.
Modified the Qt project file to support the both the version
of python 2 and python 3.
Qt5 is recommended to test pgAdmin4 in dektop mode.
If the web server is slow to start, we may need to retry the initial
page load. Implement a retry system that will retry the initial load
4 times, after 1, 2, 3 and 4 seconds, before giving up and leaving
the user with an error message and a link to retry manually.
Upon startup, the runtime will attempt to locate pgAdmin4.py in a
number of different relative locations. Once found, it will execute
it in a new thread. The main window is then created and the brower's
initial page is set to the root of the CherryPy server. At present,
that's http://127.0.0.1:8080.
