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

• outline

• directory

• bottom

• output

• syntax

• errorlist

Accessors to operating data:

• cwd

• no_refresh

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.

freezer

my $locker = $main->freezer;

Create and return an automatic freeze object that will thaw on destruction.

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)

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_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_menubar

$main->refresh_menubar;

Force a refresh of Padre's menu bar.

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.

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_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_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_command

$main->run_command( $command );

Run $command and display the result in the output panel.

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.

debug_perl

$main->debug_perl;

Run current document under Perl debugger. An error is reported if current is not a Perl document.

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.

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)

search_previous

# Previous match for a new search
$main->search_previous( $search );

# Previous match on current search (or show Find dialog if none)
$main->search_previous;

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

If no files are open, do nothing.

# Next replace for a new search
$main->replace_next( $search );

# Next replace on current search (or show Find dialog if none)
$main->replace_next;
