When launching an application, you might want to pass in some environment variables to your program.
The Environment Variables dialog lets you manage name/value pairs, including importing and exporting for use between programs or sessions.
The dialog initially has no entries.
The example below shows the equivalent of set QT_PLUGIN_PATH=%QTDIR%\plugins

•Add...
adds a new item to the list
enter name in the first column, value in the second
•Delete
deletes a selected item in the list
•Delete All
clears the list
•Acquire
fetches all system environment variables, adding them to the list
•Import...
loads variables from a previously exported file, adding them to the list
•Export...
saves all entries in the list to a file of your choice
The exported file is a simple ascii file with one entry per line of the form name=value
•OK
accepts all changes
•Cancel
ignores changes
