Redo portions of file editor to use more signals/slots rather than casting.
* file-editor-tab.cc, file-editor-tab.h (file_editor_tab::~file_editor_tab):
Add. Delete lexer to prevent memory leak. Delete _edit_area to prevent memory
leak. (file_editor_tab::conditional_close): Add. Simple slot that uses QWidget
pointer as unique ID, not for function call.
(file_editor_tab::file_name_query): Add. Simple slot that signals file name to
whomever is connected. (file_editor_tab::find,
file_editor_tab : public QWidget): Removed use of exec() and keep a pointer to
the find_dialog as a member. Toggle hide()/show() via a connected slot to
toggle visibility as desired.
* file-editor.cc, file-editor.h, file-editor-tab.cc file-editor-tab.h
(file_editor : public file_editor_interface, file_editor_tab : public QWidget,
file_editor_tab::file_editor_tab, file_editor_tab::closeEvent,
file_editor_tab::load_file, file_editor_tab::new_file,
file_editor_tab::run_file): Remove _file_editor pointer member from
file_editor_tab and rid file_editor::get_main_window from file_editor. There
should be no need for such information about higher-level hierarchy inside
lower-level objects. (file_editor::request_open_file,
file_editor_tab::open_file): Move QFileDialog to file_editor::request_open_file
and delete file_editor_tab::open_file since most of the remaining functionality
is in file_editor_tab::load_file. (file_editor::active_editor_tab): Deleted.
(file_editor::fetab_change_request, file_editor_tab::change_editor_state):
Added to initiate a request for the editor tab to change focus.
(file_editor_tab::editor_state_changed): Added arguments to pass the copy
status and the directory path so that editor doesn't have to call functions for
such information. (file_editor::handle_editor_state_changed): Add copying
directory of the file_editor_tab to the current editing directory.
(file_editor::check_conflict_save, file_editor_tab::editor_check_conflict_save,
file_editor_tab::save_file_as, file_editor_tab::handle_save_file_as_answer):
Moved a portion of the save-file-as dialog mechanism to the file_editor where
all file names can be obtained to check for conflict with already open files.
The new signal indicates to the editor that a name check be done, and in turn
the editor signals the tab to save the file.
* main-window.cc, file-editor.cc, file-editor.h, file-editor-interface.h
(file_editor::terminal, file_editor : public file_editor_interface,
file_editor_interface : public QDockWidget): Since file_editor_tab no longer
looks up to main_window, remove _main_window and _terminal from file_editor and
file_editor_interface, as well as file_editor::terminal.
* file-editor-tab.cc (file_editor_tab::file_has_changed): Make the dialog
boxes non-modal and use slots to handle user answers.
(file_editor_tab::closeEvent): Remove portion that accesses upper hierarchy
member functions, can find better approaches.
(file_editor_tab::file_editor_tab): Make there no parent for QsciScintilla so
that window modality can be set to individual editor.
* file-editor-tab.cc, file-editor.cc (file_editor_tab::load_file): Use show()
member rather than exec() and set modality to window so that rest of
application may function. Return a QString with message rather than a boolean.
* file-editor-tab.cc, (file_editor_tab::file_has_changed): Remove static
variable alreadyAsking. Multiple file_editor_tabs are using this code so do
not want to block recognition of multiple file having changed on disk
(bug #37406). Instead, simply stop tracking via the file watcher.
(file_editor_tab::save_file, file_editor_tab::save_file_as,
file_editor_tab::handle_save_file_as_answer,
file_editor_tab::handle_save_file_as_answer_close): Added a remove_on_success
variable. Changed the QFileDialog to WindowModal and created slots to handle
file selected signal and finished signal. Signal/slot connects vary based upon
remove_on_success setting. (file_editor_tab::check_file_modified): Changed the
QFileDialog to NonModal and attach some slots. Editor tab can't be parent in
case deleted, so use read-only state of the editor area.
* file-editor-tab.h (file_editor_tab : public QWidget): New signals for
file_editor for tab and file name management. (file_editor_tab::get_file_name):
Delete.
* file-editor.h (file_editor : public file_editor_interface): Make QStringList
sessionFileNames a member of file_editor so that it can retain data between
file_editor_tab signals. Also can be used for checking precense of filenames
and prevent opening multiple copies (bug #36869) Added signals for file editor
tabs--settings_changed, fetab_close_request, and query_file_name. Three new
slots for tab and file name management.
* file-editor-interface.h, file-editor.h
(file_editor_interface::add_file_editor_tab, file_editor::add_file_editor_tab):
Made the text name for the tab an input variable.
* file-editor.cc (file_editor::~file_editor): Replace dynamic_cast with simple
signal querying all file editor tabs for file names which end up in
savedSessionTabs. (file_editor::handle_file_name_changed): Dynamic cast not
necessary since QObject and QWidget are compatible.
(file_editor::handle_tab_close_request): Replace dynamic_cast with signal to
request file_editor_tab with associated tabID tag should close.
(file_editor::handle_tab_remove_request): Rename of handle_tab_close_request.
Instead of dynamic cast, loop through pointers comparing QWidget* to QObject*,
if same tag remove tab via index and also delete which fixes a memory leak.
(file_editor::handle_add_filename_to_list): Simple slot that uses append() of
the list member functions. (file_editor::notice_settings): Rather than dynamic
cast, emit signal for the file_editor_tabs. (file_editor::add_file_editor_tab):
New variety of connections for improved flow. (file_editor::request_open_file):
Given error messages are made WindowModal, the tab shouldn't be delete if file
open is not successful. The file_editor_tab takes care of that.
(file_editor::request_open_file): Added check and message box for the
requested file already open in editor. For the non-interactive overloaded
version, open a message dialog box to tell the user file not found, e.g.,
could not find file in the settings when launched.
(file_editor::request_open_file): Inquire file names and update list before
checking for existence of files. Supply empty title to editor tab then have
file_editor_tab update name.
* file-editor-tab.h, file-editor-tab.cc, file-editor.cc
(file_editor_tab::run_file): New signal process_octave_code.
(file_editor::add_file_editor_tab): Connect signal process_octave_code to
file_editor's parent's slot handle_command_double_clicked.
