annotate gui/src/FilesDockWidget.cpp @ 14602:c8453a013000 gui

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Cleaned up code. Fixed bug that causes the GUI to freeze when launching another editor. * FileEditor: Now the call of another process returns immediately. Adjusted text when closing a file. * MainWindow: Moved creating a lexer into the constructor.
