İzleyici

İzleyici, dosyalarınız için kullanılan grafik arabirimdir. Yeni dosyalar oluşturmanıza veya var olanları bulmanıza, çalıştırmanıza, yeniden adlandırmanıza, kopyalamanıza veya silmenize olanak verir.

Diğerleri gibi bir uygulama olmasından ötürü (Masaüstü, özünde tam ekran çalışan bir pencereden ibarettir), İzleyici pencereleri ile Masaüstü Çubuğu'nda belirir ve isterseniz kendisinden çıkabilir veya onu yeniden başlatabilirsiniz. Çöken veya takılan bir İzleyici'den çıkıp yeniden başlatmanın en kolay yolu Takım Monitörü'nü çağırmaktır.

Diskleri Bağlama

Bir sabit disk, CD, USB Bellek vb. türü aygıtlara erişebilmek için onu önce bağlamalısınız, diğer bir deyişle sisteme onun orada olduğunu söylemelisiniz. Bu Masaüstü'nde veya daha önceden bağlanan bir diskin üzerinde (örn. önyükleme diski) sağ tıklayıp Bağla altmenüsünden bağlamak istediğiniz diski seçerek yapılır. Aynı Bağla menüsünü Masaüstü Çubuğu'nda da bulabilirsiniz.

Sistemi yeniden başlattığınızda aynı diskleri her seferinde yeniden bağlamaktan kurtulmak için Ayarlar bölümüne bakın.
Yukarıdaki ayarlar taktığınız her depolama aygıtını ve daha önceden bağlanmış tüm diskleri önyükleme sırasında kendiliğinden bağlamanıza olanak verir.

Dolaşım

Bir klasöre çift tıkladığınızda, öntanımlı olarak İzleyici tıkladığınız pencereyi olduğu gibi bırakıp yeni bir pencere açar. Bu kolaylıkla kalabalıklaşmış bir masaüstüne neden olabilir.
Bunu OPT düğmesini basılı tutarak önleyebilirsiniz; böylece üst pencere kendiliğinden kapanır.
Bu durum klavye dolaşımı için de geçerlidir. Ayrıntılı bilgi için Kısayol ve düğme kombinasyonları bölümüne bakın.

Klasörler arasında dolaşım, diğer platformlardaki dosya yöneticilerinde olduğu gibi İzleyici'nin ana ereklerinden biridir. Haiku İzleyici bunu kolay ve etkili bir biçimde yapabilmeniz için kendine özel birçok özellik barındırmaktadır.

Açılır altmenülerde dolaşım

Varacağınız yere sürekli çift tıklamaktansa aşağı düzeylere inmenin daha kolay bir yolu vardır:

Bir klasöre sağ tıklayın; bildiğiniz bağlam menüsünün en üstünde aşağı düzeylere bakabilmenizi sağlayan bir açılır menü bulacaksınız. Aradığınız klasöre veya konuma ulaşıncaya değin menüler içinde gezinmeyi sürdürün ve vardığınızda ögenin üzerine tıklayın. Üst görsel /boot/home/config/ klasörünün içeriğini göstermektedir.
Yukarıdaki işlemi bir dosyayı birlikte sürükleyerek yaparsanız dosya bıraktığınız konuma taşınacaktır.

Benzer bir yöntem ve uygulama tüm İzleyici pencerelerinden yapılabilir:

Sol aşağıda öge sayılarının belirtildiği alana tıklayın; o konumdan aşağı gidebileceğiniz tüm konumların listesini belirten altmenüleri göreceksiniz. Buradan istediğiniz konuma geçebilirsiniz.

Masaüstü'nün nice her zaman en üst düzeyde olduğuna dikkat edin; bu İzleyici'nin bağlı diskleri listelediği konum olduğundan dolayıdır. Başka bir diske geçmek isterseniz önce en üst düzeye (Masaüstü'ne) gelip oradan başka disklere geçmeniz gerekmektedir.

You'll get the same submenu-navigating when you drag a file over a folder. After a short while of hovering, a submenu pops up and you can drill down to your destination. If you initiated the drag with the right mousebutton, you can choose between copying, moving or linking the file when you release the mouse.

Jumping to files with type-ahead

You may be familiar with the concept from file managers of other operating systems: typing the first few letters of a filename will jump to the first file matching these starting characters. Haiku took the idea a step further. If there isn't a file starting with those letters it will jump to the first file including the string anywhere in its name. And if there's nothing with the string in its filename, the attributes are searched next.

In the above example, there are many files starting with "Haiku logo", rendering simpler approaches to typing ahead quite useless. In Haiku however, typing "web" jumps right to its first occurence in "Haiku logo - website". The characters you enter appear in the bottom left corner where you normally find the item count of all files in the folder. A second after entering a character, the display jumps back to normal and you're ready for a new type ahead search.

Type-ahead filtering

Instead of jumping to a file while typing, there's also the option to filter out all files not matching your type-ahead string. This can improve clarity dramatically, especially when dealing with crowded folders. By using SHIFT SPACE as delimiter, you can even filter on multiple strings.
Contrary to type-ahead jumping, the filtering will stick until you press ESC or close the window (or leave the folder if you're using Single Window Navigation).
This type-ahead filtering is set in the Tracker preferences.

Appearance

Tracker windows offer three different viewing modes from the Window menu:

• Icon view (ALT 1) - Big icons, you can change the size from the submenu or in/decrease their size with ALT +/-.

• Mini icon view (ALT 2) - Small icons.

• List view (ALT 3) - A detailed list of your files enabling you to show/hide file attributes (see topic Attributes.)

The Window menu offers a number of other functions:

• Resize to fit (ALT Y) - Resizes the window to its ideal size.

• Arrange by... - Only available in Icon or Mini icon view, a submenu allows to set the sorting order to various properties:

  • Name, Real name, Size, Modified, Created, Kind, Location, Permissions

  • Reverse order - Inverts the sorting order

  • Clean up (ALT K) - Aligns all icons to an invisible grid. Hold down SHIFT and the menu becomes Clean up all which additionally sorts all icons according to the above selected criterium.

• Select... (SHIFT ALT A) - Select files according to a regular expression.

• Close (ALT W) - Closes the window. Hold down SHIFT and the menu becomes Close all which closes every Tracker window.

• Close all in workspace (ALT Q) - Closes every Tracker window in the current workspace. A useful shortcut if you forgot to hold the OPT key while clicking through folders and all those still open Tracker windows clutter your workspace.

Sometimes you just want to rearrange a few icons without doing a complete Clean up (ALT K). In that case, you select these icons and start to drag them to their new location. Before you drop them there, keep ALT pressed. This will align the icons to the invisible grid.

The rest of the functions are pretty self-explanatory, leaving the Tracker preferences.

Tracker preferences

Window | Preferences... opens a panel that offers a number of settings that, where not obvious, should become clear once tried out. Since all settings are applied live, you'll immediately see the changes.
So, in short, the not so obvious settings:

• Desktop - Decide if all mounted disks appear directly on the Desktop or in a window after clicking a single Disk icon sitting on the Desktop.

• Windows - You can set Single window navigation, i.e. a double-clicked folder doesn't open in its own window, but inside the already open window instead, replacing the view of its parent folder. This is not the same as clicking while holding the OPT key, as described above, because you'll lose the per window saved position and size.

  

  Before you switch Tracker to Single window navigation mode, because that may feel more familiar to you, we recommend giving the menu based browsing a try first, as that may actually work much faster for you after getting used to. On the other hand, single window browsing offers a Navigator where you can enter or copy & paste a path name and use back, forward and up buttons.

  Activating Type-ahead filtering will filter the contents of a Tracker window while you type to only display the files matching your string in their name or any currently displayed attribute. See above.

• Volume icons - Set the color of an optional indicator of free space that's shown besides a disk's icon.

• Disk mount - Define when and what disks are mounted automatically, as described above under "Mounting volumes".

This panel, by the way, is also available as Tracker from Deskbar's Preferences.

Working with files

When invoked on a selected file, most of the File menu commands are also offered in the context menu by right-clicking that file.

As usual the commands are pretty clear.

• Find... - Find a file or folder. See topic Query for more info.

• New - Create a new folder or any other file based on a template.

  

  Choosing Edit templates... opens the folder /boot/home/config/settings/Tracker/Tracker New Templates. Creating a file in that folder will offer its filetype with the file's name and other attributes as template in the New menu. Here, there's a file "Text" with the filetype text/plain. See topic Filetypes for more info.

• Open with... - A submenu offers all applications that can handle this filetype.

  

  The preferred application that would open the file when double-clicked, is checkmarked. This submenu lists first those applications that can handle the exact filetype, in this case it's a text file, the type text/plain. Next come all applications that can handle that supertype in general, here text/*. Last in the list are those that can deal with any file. If you don't click on an app in the submenu, but on the Open with... entry instead, a panel opens:

  

  Here you'll again find the programs that were listed in the submenu. By selecting one and clicking the Open and make preferred button, you changed the preferred application for every file of that filetype, here text/plain.

• Get info

  This opens a panel that shows the meta data of a file and lets you edit its permissions. You can rename it by clicking on the file name at the top.

  

  The panel consists of three tabs:

  • Information: Shows standard data like size, date of creation/modification, file type and location. Click on the location path to open the files parent folder. The Open with menu sets the preferred application to open this particular file.
  • Permissions: Lets you change owner, group and file permissions.
  • Attibutes: Lists all extra file attributes with their value and type.

• Edit name, Duplicate and Move to trash - lets you rename or duplicate a file or put the selected file(s) to the trash.

• Move to, Copy to and Create link - lets you move, copy or link the selected file(s) using the submenu navigating method. Holding SHIFT while invoking the menu offers the option to create a relative link.

• Cut, Copy and Paste - lets you cut, copy and paste files using the clipboard. By holding SHIFT while invoking the menu you can Copy/Cut more files, maybe from another folder that you can paste somewhere else later. Also, while holding SHIFT you can paste the copied files in the clipboard as links.

• Identify - will sniff out and set the type of files if they didn't have one before, e.g. if you transferred a file with wget which doesn't set a filetype itself. Holding SHIFT while invoking the menu changes the item to Force identify which identifies the filetype and corrects it if it was false before.

• Add-Ons - offers you every generic Tracker add-on and those that can handle the selected file(s). See topic Tracker Add-ons for more information.

Transaction status

When you copy, move or delete files, Tracker shows its progress with a status window. If you initiate more than one transaction, each job gets its own status display.

To the right are two buttons to pause or stop a transaction entirely. Sometimes it can be useful to temporarily pause a large transaction. For example, you may need to quickly launch a large application. Copying large amounts of data chokes your harddisk's IO bandwidth and thus delays your workflow.
