- Compilation error with Qt4 as "QUrlQuery" class was introduced since Qt5.
- Client side download code has been removed as now we support server side download.
- We should not delete sender object inside slot. If we do so it may crash the application. To avoid this, we used Qt's "deleteLater" which will delete the objects once the processing of all the events have been done.
PYTHONPATH) to run the runtime with the virtual environment properly.
And, also allow to use the python interpreter to be used with the
background process modules.
- Add binary directory of the virtual environment to PATH environment
variable.
- Add lib, dynamic libraries (python specific), and site-package
directories of the virtual environment in the PYTHONPATH environment
variable.
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.
instead. Add support to the runtime to allow the user to specify the
Python path. This needs to be more automated for release, but will be
useful for debugging and development.
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.
This runtime implements a brower control with embedded Python
interpretor. The Python interpretor runs a simple script at
startup to generate some HTML that is displayed in the browser.
Arbitrary URLs can be opened from the "Open URL" option on the
File menu.
