Padre::Wx::Main

NAME

Padre::Wx::Main − The main window for the Padre IDE

DESCRIPTION

"Padre::Wx::Main" implements Padre’s main window. It is the window containing the menus, the notebook with all opened tabs, the various sub− windows (outline, subs, output, errors, etc).

It inherits from "Wx::Frame", so check Wx documentation to see all the available methods that can be applied to it besides the added ones (see below).

PUBLIC API

Constructor
There’s only one constructor for this class.

"new"

    my $main = Padre::Wx::Main−>new($ide);

Create and return a new Padre main window. One should pass a "Padre" object as argument, to get a reference to the Padre application.

Accessors
The following methods access the object attributes. They are both getters and setters, depending on whether you provide them with an argument. Use them wisely.

Accessors to GUI elements:

"title"

"config"

"aui"

"menu"

"notebook"

"left"

"right"

"functions"

"todo"

"outline"

"directory"

"bottom"

"output"

"syntax"

"errorlist"

Accessors to operating data:

"cwd"

Accessors that may not belong to this class:

"ack"

"find"

    my $find = $main−>find;

Returns the find dialog, creating a new one if needed.

"fast_find"

    my $find = $main−>fast_find;

Return current quick find dialog. Create a new one if needed.

"replace"

    my $replace = $main−>replace;

Return current replace dialog. Create a new one if needed.

Public Methods
"load_files"

    $main−>load_files;

Load any default files: session from command-line, explicit list on command− line, or last session if user has this setup, a new file, or nothing.

"lock"

  my $lock = $main−>lock('UPDATE', 'BUSY', 'refresh_toolbar');

Create and return a guard object that holds resource locks of various types.

The method takes a parameter list of the locks you wish to exist for the current scope. Special types of locks are provided in capitals, refresh/method locks are provided in lowercase.

The "UPDATE" lock creates a Wx repaint lock using the built in Wx::WindowUpdateLocker class.

You should use an update lock during GUI construction/modification to prevent screen flicker. As a side effect of not updating, the GUI changes happen significantly faster as well. Update locks should only be held for short periods of time, as the operating system will begin to treat your\ application as "hung" if an update lock persists for more than a few seconds. In this situation, you may begin to see GUI corruption.

The "BUSY" lock creates a Wx "busy" lock using the built in Wx::WindowDisabler class.

You should use a busy lock during times when Padre has to do a long and/or complex operation in the foreground, or when you wish to disable use of any user interface elements until a background thread is finished.

Busy locks can be held for long periods of time, however your users may start to suspect trouble if you do not provide any periodic feedback to them.

Lowercase lock names are used to delay the firing of methods that will themselves generate GUI events you may want to delay until you are sure you want to rebuild the GUI .

For example, opening a file will require a Padre::Wx::Main refresh call, which will itself generate more refresh calls on the directory browser, the function list, output window, menus, and so on.

But if you open more than one file at a time, you don’t want to refresh the menu for the first file, only to do it again on the second, third and fourth files.

By creating refresh locks in the top level operation, you allow the lower level operation to make requests for parts of the GUI to be refreshed, but have the actual refresh actions delayed until the lock expires.

This should make operations with a high GUI intensity both simpler and faster.

The name of the lowercase MUST be the name of a Padre::Wx::Main method, which will be fired (with no parameters) when the method lock expires.

locked
This method provides the ability to check if a resource is currently locked.

Single Instance Server
Padre embeds a small network server to handle single instance. Here are the methods that allow to control this embedded server.

"single_instance_start"

    $main−>single_instance_start;

Start the embedded server. Create it if it doesn’t exist. Return true on success, die otherwise.

"single_instance_stop"

    $main−>single_instance_stop;

Stop & destroy the embedded server if it was running. Return true on success.

"single_instance_running"

    my $is_running = $main−>single_instance_running;

Return true if the embedded server is currently running.

"single_instance_connect"

    $main−>single_instance_connect;

Callback called when a client is connecting to embedded server. This is the case when user starts a new Padre, and preference "open all documents in single Padre instance" is checked.

"single_instance_command"

    $main−>single_instance_command( $line );

Callback called when a client has issued a command $line while connected on embedded server. Current supported commands are "open $file" and "focus".

Window Methods
Those methods allow to query properties about the main window.

"window_width"

    my $width = $main−>window_width;

Return the main window width.

"window_height"

    my $width = $main−>window_height;

Return the main window height.

"window_left"

    my $left = $main−>window_left;

Return the main window position from the left of the screen.

"window_top"

    my $top = $main−>window_top;

Return the main window position from the top of the screen.

Refresh Methods
Those methods refresh parts of Padre main window. The term "refresh" and the following methods are reserved for fast, blocking, real-time updates to the GUI , implying rapid changes.

"refresh"

    $main−>refresh;

Force refresh of all elements of Padre main window. (see below for individual refresh methods)

"add_refresh_listener"

Adds an object which will have its "−>refresh()" method called whenever the main refresh event is triggered. The refresh listener is stored as a weak reference so make sure that you keep the listener alive elsewhere.

If your object does not have a "−>refresh()" method, pass in a code reference − it will be called instead.

Note that this method must return really quick. If you plan to do work that takes longer, launch it via the Action::Queue mechanism and perform it in the background.

"refresh_title"

Sets or updates the Window title.

"refresh_syntaxcheck"

    $main−>refresh_syntaxcheck;

Do a refresh of document syntax checking. This is a "rapid" change, since actual syntax check is happening in the background.

"refresh_outline"

    $main−>refresh_outline;

Force a refresh of the outline panel.

"refresh_menu"

    $main−>refresh_menu;

Force a refresh of all menus. It can enable / disable menu entries depending on current document or Padre internal state.

"refresh_menu_plugins"

    $main−>refresh_menu_plugins;

Force a refresh of just the plug-in menus.

"refresh_windowlist"

    $main−>refresh_windowlist

Force a refresh of the list of windows in the window menu

"refresh_recent"

Specifically refresh the Recent Files entries in the File dialog

"refresh_toolbar"

    $main−>refresh_toolbar;

Force a refresh of Padre’s toolbar.

"refresh_status"

    $main−>refresh_status;

Force a refresh of Padre’s status bar.

"refresh_cursorpos"

    $main−>refresh_cursorpos;

Force a refresh of the position of the cursor on Padre’s status bar.

"refresh_functions"

    $main−>refresh_functions;

Force a refresh of the function list on the right.

"refresh_directory"

Force a refresh of the directory tree

"refresh_aui"
This is a refresh method wrapper around the "AUI" "Update" method so that it can be lock-managed by the existing locking system.

Interface Rebuilding Methods
Those methods reconfigure Padre’s main window in case of drastic changes (locale, etc.)

"change_style"

    $main−>change_style( $style, $private );

Apply $style to Padre main window. $private is a Boolean true if the style is located in user’s private Padre directory.

"change_locale"

    $main−>change_locale( $locale );

Change Padre’s locale to $locale. This will update the GUI to reflect the new locale.

"relocale"

    $main−>relocale;

The term and method "relocale" is reserved for functionality intended to run when the application wishes to change locale (and wishes to do so without restarting).

Note at this point, that the new locale has already been fixed, and this method is usually called by "change_locale()".

"reconfig"

    $main−>reconfig( $config );

The term and method "reconfig" is reserved for functionality intended to run when Padre’s underlying configuration is updated by an external actor at run-time. The primary use cases for this method are when the user configuration file is synced from a remote network location.

Note: This method is highly experimental and subject to change.

"rebuild_toolbar"

    $main−>rebuild_toolbar;

Destroy and rebuild the toolbar. This method is useful because the toolbar is not really flexible, and most of the time it’s better to recreate it from scratch.

Tools and Dialogs
Those methods deal with the various panels that Padre provides, and allow to show or hide them.

"show_functions"

    $main−>show_functions( $visible );

Show the functions panel on the right if $visible is true. Hide it otherwise. If $visible is not provided, the method defaults to show the panel.

"show_todo"

    $main−>show_todo( $visible );

Show the to do panel on the right if $visible is true. Hide it otherwise. If $visible is not provided, the method defaults to show the panel.

"show_outline"

    $main−>show_outline( $visible );

Show the outline panel on the right if $visible is true. Hide it otherwise. If $visible is not provided, the method defaults to show the panel.

"show_debugger"

    $main−>show_debugger( $visible );

"show_directory"

    $main−>show_directory( $visible );

Show the directory panel on the right if $visible is true. Hide it otherwise. If $visible is not provided, the method defaults to show the panel.

"show_output"

    $main−>show_output( $visible );

Show the output panel at the bottom if $visible is true. Hide it otherwise. If $visible is not provided, the method defaults to show the panel.

"show_syntax"

    $main−>show_syntax( $visible );

Show the syntax panel at the bottom if $visible is true. Hide it otherwise. If $visible is not provided, the method defaults to show the panel.

Introspection
The following methods allow to poke into Padre’s internals.

"current"

    my $current = $main−>current;

Creates a Padre::Current object for the main window, giving you quick and caching access to the current various object members.

See Padre::Current for more information.

"pageids"

    my @ids = $main−>pageids;

Return a list of all current tab ids (integers) within the notebook.

"pages"

    my @pages = $main−>pages;

Return a list of all notebook tabs. Those are the real objects, not the ids (see "pageids()" above).

"editors"

    my @editors = $main−>editors;

Return a list of all current editors. Those are the real objects, not the ids (see "pageids()" above).

Note: for now, this has the same meaning as "pages()" (see above), but this will change once we get project tabs or something else.

"documents"

    my @document = $main−>documents;

Return a list of all current documents, in the specific order they are open in the notepad.

Process Execution
The following methods run an external command, for example to evaluate current document.

"on_run_command"

    $main−>on_run_command;

Prompt the user for a command to run, then run it with "run_command()" (see below).

Note: it probably needs to be combined with "run_command()" itself.

"on_run_tdd_tests"

   $main−>on_run_tdd_tests;

Callback method, to build and then call on_run_tests

"on_run_tests"

    $main−>on_run_tests;

Callback method, to run the project tests and harness them.

"on_run_this_test"

    $main−>on_run_this_test;

Callback method, to run the currently open test through prove.

"run_document"

    $main−>run_document( $debug )

Run current document. If $debug is true, document will be run with diagnostics and various debug options.

Note: this should really be somewhere else, but can stay here for now.

Session Support
Those methods deal with Padre sessions. A session is a set of files / tabs opened, with the position within the files saved, as well as the document that has the focus.

"capture_session"

    my @session = $main−>capture_session;

Capture list of opened files, with information. Return a list of "Padre::DB::SessionFile" objects.

"open_session"

    $main−>open_session( $session );

Try to close all files, then open all files referenced in the given $session (a "Padre::DB::Session" object). No return value.

"save_session"

    $main−>save_session( $session, @session );

Try to save @session files ("Padre::DB::SessionFile" objects, such as what is returned by "capture_session()" − see above) to database, associated to $session. Note that $session should already exist.

User Interaction
Various methods to help send information to user.

"message"

    $main−>message( $msg, $title );

Open a dialog box with $msg as main text and $title (title defaults to "Message"). There’s only one OK button. No return value.

"prompt"

    my $value = $main−>prompt( $title, $subtitle, $key );

Prompt user with a dialog box about the value that $key should have. Return this value, or "undef" if user clicked "cancel".

Search and Replace
These methods provide the highest level abstraction for entry into the various search and replace functions and dialogs.

However, they still represent abstract logic and should NOT be tied directly to keystroke or menu events.

"search_next"

  # Next match for a new search
  $main−>search_next( $search );
  # Next match on current search (or show Find dialog if none)
  $main−>search_next;

Find the next match for the current search, or spawn the Find dialog.

If no files are open, silently do nothing (don’t even remember the new search)

  $main−>replace_next;

Replace the next match for the current search, or spawn the Replace dialog.

If no files are open, do nothing.

"replace_all"
