Що таке панель Латте? З чого розпочався проект?

Панель Латте — панель на основі бібліотек Плазми, безпосередній наступник панелі Now. Латте є результатом об'єднаних зусиль розробників панелі Now та панелі Candil.

Як додати кнопки запуску?

Найпростішим і найочевиднішим способом є перетягування зі скиданням на панель задач (це ділянка, під запущеними вікнами, де показано крапки і лінії).

Підказка: ви можете додати їх поза межами ділянки керуванян задачами, але це спричинить проблеми із анімацієї для розмірів <64 пікселів та надмірного споживання пам'яті.

Як додати аплети?

Клацніть правою кнопкою миші на стільниці Плазми, виберіть Додати віджети. З панелі навігації списком віджетів Плазми перетягніть і скиньте будь-який потрібний вам віджет на вашу панель Латте.

Як увімкнути режим редагування у Латте?

У режимі редагування користувач може вилучати аплети, перевпорядковувати їх і отримувати доступ до додаткових параметрів у різних областях. Щоб увімкнути його, слід просто викликати вікно параметрів Латте.

Як пересувати або вилучати аплети?

You should go to Edit Mode (when the settings window is shown) and then you can drag any applet you want to be placed elsewhere. You can also remove it while under "Edit Mode" by right clicking on it or by pressing the [X] button in the tooltip above the applet.

Чи можна вимкнути параболічний ефект для певного аплета?

You should go to Edit Mode (when the settings window is shown) and hover afterwards the specific applet. Its tooltip contains a lock icon that will disable parabolic effect for that applet when clicked.

My launcher and its window are not associated correctly OR my launcher is using a low-resolution icon?

This issue means that plasma libtaskmanager has not associated your launcher and app windows correctly to the relevant desktop file. Plasma is trying to be smart enough in order to correctly identify which desktop files are associated to which specific windows, but there are cases when it fails. Best way to solve this is to check the StartupWMClass record in the desktop file. This record should point at the proper WM_CLASS record at all times. For example even though the Latte Dock desktop file is called org.kde.latte-dock.desktop, its StartupWMClass is lattedock. In order to correctly identify the StartupWMClass of an application, you can use xprop.

Приклад:

Віддайте команду xprop у консолі
Клацніть на вікні, яким ви цікавитеся
Знайдіть наприкінці виведених до консолі даних запис WM_CLASS(STRING) =
Додайте раніше згаданий запис до файла desktop програми у полі StartupWMClass

Наприклад, у Gimp 2.10, навіть хоча файл desktop має назву gimp.desktop, StartupWMClass має значення gimp-2.10' . Для Gimp StartupWMClass не потрібно додавати, оскільки розробник Плазми подбали про правильну прив'язку за допомогою /etc/xdg/taskmanagerrulesrc.

Як (авто)запускається панель Латте і чому до складу пакунка включено віджет?

Latte starts from the menu; there is no need to place the widget on your desktop. It is there for testing purposes. Automatic start can be enabled through Settings Window -> Tweaks.

Джерелом натхнення слугувала якась інша панель? Яке місце займає панель Латте серед інших панелей?

Архітектуру Латте розроблено і засновано на оболонці Плазми, але джерелом натхнення також слугувала панель Plank (з неї, наприклад, запозичено режими видимості).

Яку технологію і мову програмування використано?

Латте здебільшого написано на Qt/QML і C++14, але цей проект був би неможливим без KDE Frameworks 5.

Гаразд, ви переконали мене спробувати! Як встановити панель і які у неї залежності?

You can download the sources, install the required dependencies and build Latte. Please read the README and INSTALLATION. But if you have any problems or doubts, you can ask the development team.

У яких дистрибутивах є пакунок? Чи можна його встановити за допомогою програми для керування пакунками?

Будь ласка, ознайомтеся із нижньою частиною головної сторінки панелі Латте, розділом Сховища.

Чому після анімації підстрибування кнопки запуску показ вікна відбувається із ривками?

Спробуйте виконати такі дії:

Відкрийте сторінку Системні параметри -> Програми -> Супровід запуску -> (вимкніть анімацію) Керування задачами
If the problem persists, then your application desktop file might be missing the "StartupWMClass" record. In Inkscape's case, that would be: StartupWMClass=inkscape. You can use the xprop application in order to identify its correct value.

Якими є базові параметри налаштовування?

Latte is highly configurable. We invite you to explore and configure latte to your liking from the config window. 👍 But some special features are: Visibility, Zoom Effect and Add widgets/plasmoids from KDE Plasma.

Де зберігаються файли налаштувань?

Будьте обережні! Рекомендуємо створити резервну копію, якщо вам потрібно зберегти початкові налаштування.

cat ~/.config/lattedock-appletsrc

cat ~/.config/lattedockrc

У ~/.config/lattedock-appletsrc зберігаються якісь файли. Можете пояснити, для чого вони?

Config is organized based on "Containments" (e.g. [Containments][1]). Each of those have a number to distinguish one from the other, and each one has different blocks of options. That's where "applets" come into play and each "Containment" has its applets (usually one - [Containments][1][Applets][2]). So it goes like:

[Containments][NumberOfContainment][Applets][NumberOf_Applet]

Now, applet-2 may be a series of launchers, a Plasma Widget, anything. Each and every applet also has multiple blocks of configuration. A block might be used for generic "applet" configuration (e.g. [Containments][1][Applets][2]) or some more specific options (e.g. [Containments][1][Applets][2][Configuration][General]).

As you can tell, we can't document everything about those numerous options here, but here is the deal: You can tweak every applet separately, you can change the order applets appear with appletOrder=No_of_Applet;No_of_Another, under [Containments][1][General]* , you can manually change the iconSize at the same block, if you want shadows, what the zoomLevel must be, etc. A sample is provided here so you can see it for yourself.

Як бачите, він містить усі інші аплети, і ви можете скоригувати налаштування у загальних параметрах

Чи є якісь параметри налаштування для досвідчених користувачів, які ніколи не варто чіпати?

None is forbiden, as long as you take frequent backups of your configuration. Use cron or similar software to automate the procedure and place them in a safe place.

Як увімкнути загальні клавіатурні скорочення Латте?

У більшості випадків вам слід перейти до сторінки Системні параметри -> Загальні скорочення -> Панель Латте і увімкніть потрібні вами клавіатурні скорочення.

Super + цифра: активувати завдання
Super + Ctrl + цифра: новий екземпляр завдання
Super + `: показати приховану панель

Can I use my super key to open the app launcher?

Спочатку переконайтеся, що Панель Латте закрито.

Option 1:

Of course you can, but you will need to add at your ~/.config/kwinrc file the following code:

[ModifierOnlyShortcuts]
Meta=org.kde.lattedock,/Latte,org.kde.LatteDock,activateLauncherMenu

Потім перезавантажте KWin за допомогою такої команди:

qdbus org.kde.KWin /KWin reconfigure

Option 2:

Alternatively, you can run the following commands:

kwriteconfig5 --file ~/.config/kwinrc --group ModifierOnlyShortcuts --key Meta "org.kde.lattedock,/Latte,org.kde.LatteDock,activateLauncherMenu"
qdbus org.kde.KWin /KWin reconfigure

Latte v0.8 deactivates Borderless Maximized Windows from Active Window Control plasmoid, what can I do ?

Latte v0.8 supports BorderLess Maximized Windows per layout simultaneously. In order for this to work it had to support that feature internally. You can try the following:

Disable BorderLess Maximized Windows from Active Window Control.
Go to Latte Settings -> Layouts -> Choose tab (Preferences) and enable Support borderless maximized windows in different layouts.
Return to your layouts and a new column called Borderless should now appear, add a check mark in the column for the layout you want that feature and click Apply.

Ok, so now I can't launch Latte. Is there any sample config to restore it to default settings?

You have been told to take backups. Unfortunately, unless you post your configuration to get help, little can be done now; just killall -9 latte-dock, delete your configuration and restart Latte in order to reconfigure it. A configuration exists [here](http://pastebin.ca/3772307), but it will most likely not be useful to you.

Can I tweak things like Latte Dock's distance from the screen's border?

You can minimize the distance, but not directly tweak it. Go to Latte Setting -> Tweaks and select Shrink thickness margins.

Чи є якісь попередньо завантажені компонування для Латте 0.6?

In Latte v0.7, the layouts have been added by default in the Appearance page. For previous v0.6, users are able to use the Preloaded Layouts file, which contains four of the most used layouts (Default, Unity, Plasma, Favourite).

Can I tweak a launcher's icon or its command parameters?

You can set it up on your plasma environment and drag n' drop it onto your "Latte Dock".

Чи можна перевпорякувати невідповіним чином розташовані кнопки запуску та аплети за допомогою файлів налаштувань?

If you misplaced a launcher (or a whole applet), open ~/.config/lattedock-appletsrc. Search your launcher and decide where you want to place it. Cut

;file:///usr/share/applications/myapp.desktop

(yes, with the semicolon too) and paste it after the launcher - and its semicolon - you want. Be very careful; only the last launcher won't need a semicolon afterwards! So if you are copying your launcher between two others, you have to make sure that a semicolon exists both before and after your launcher. Let's see an example; let's say you need to copy the launcher for transmission-qt:

..;file:///usr/share/applications/kchmviewer.desktop;file:transmission-qt;file:....

If what you want to reposition is a whole applet, rather than a launcher in an applet, you will find appletOrder very useful. Just note your applet's number and change the order in which applets are written in the previously mentioned option. Have I mentioned to keep a backup before you edit? I'm mentioning again; it's good practice.

What effects does Latte Dock provide? Can launchers rotate, shake or dim when clicked?

Latte only has the zoom effect and shadows, but we are very concerned about delivering an excellent user experience.

How can someone shutdown any effect, so the icons do absolutely nothing when clicked?

You can disable all animations through Latte Configuration Window -> Appearance -> Animations -> None.

Launchers are disappearing before the relevant window is shown even though they shouldn't.

We are acquainted with this, but this behavior is provided by plasma's libtaskmanager. You can read more at: Latte Issue #72, KDE bug report

I set Animations to None, but when clicking on a launcher its icon momentarily disappears.

This bug was already fixed in current master and will be included in the next (0.6.0) release. So all you have to do is git pull the latest changes of master, or wait for the next stable version if you prefer.

Some applets in my dock are shown too small from Plasma 5.10 and beyond, can I fix this?

In Plasma 5.10, the plasma developers decided that the applets in the panels should have a maximum size that must not be overcome. You can change this at plasma System Settings-> Icons -> Advanced -> Panel -> by setting a size of 256px.

My left dock behaves strangely from Plasma 5.10 onwards, how can I fix this?

In Plasma 5.10, the KWin developers introduced gesture functionality for touch screens, which is enabled by default for all systems. You can disable it through plasma System Settings -> Workspace Behavior -> Touchscreen. Relogin your plasma session if the change doesn't take effect immediately.

So far so good, but Wayland is the future. What are the plans on this?

We plan to work on this for Plasma 5.10, but we are currently working on offering experimental support as well.

When support for Wayland is provided, will Latte Dock remove its automagical dependency of X11?

It's still a long way off for Wayland to replace X11, but it's possible to build Latte without X11 dependencies, however we are still working on supporting Wayland.

As of writing this F.A.Q., what is the problem with Qt v5.8?

If you are brave enough to mess with technical details, you may want to look here and here.

Чи можна наказати панелі Латте запускатися лише у сеансі Плазми?

Так, це можна зробити. Виконайте такі настанови:

Go to System Settings -> Startup and Shutdown -> Autostart.
Choose Latte Dock from the applications list.
Advanced -> Autostart only in Plasma.

Is there any other hiccup or potential problem I should be careful of?

Software, as everything else in life, isn't perfect; we constantly try to make better software and you can help us out by reporting every possible problem you may find. To answer the question though, there isn't a bug serious enough to prevent you from trying Latte Dock.

Чи є у авторів програми якісь сподівання та побажання щодо можливостей самої Плазми?

The most important feature needed from KWin in Wayland is that distros provide access to KWayland's privileged APIs and/or for the users, a confirmation from them that Latte requests such APIs.

How often will new versions be released and what are your plans?

The first priority needed to release a stable version is that all the needed features are implemented and no major crashes appear. We are of course trying to keep the schedule, but on the other hand, it will be ready when it is ready is the better philosophy we should follow in order to provide a complete and stable release for our users.

I am a complete newbie but I want to help somehow. What can I do?

By the time this F.A.Q. was written, much help is needed to make Latte stable with multi-screen setups. You could clone the "multiscreens" branch and report back any issues. Normal bug reports, reports about problems with specific Plasma or Qt versions, strange desktop behavior or even wishes about new features are all welcome as well.

I know how to program. What can I do to help?

First step is to know what you are after and then to fork the repo; after that, you can hunt for bugs, add new features - or make already existing features more stable. Discuss your changes and if they are good and reasonable enough, we are more than happy if you provide a pull request.

How can I install from the current master branch?

You can easily download and install from the latest master branch by running a script with the following commands:

git clone https://github.com/psifidotos/Latte-Dock.git
cd Latte-Dock
sh install.sh

The last command might ask for your root password just before installing.

How can I install from a specific branch?

If you want to test some features that currently don't exist in the master branch, you have to checkout the branch you wish to install. Let's say you need the multi2 branch:

git clone https://github.com/psifidotos/Latte-Dock.git
cd Latte-Dock
git pull
git branch multi2
git checkout multi2
git pull origin multi2

Зберіть у звичайному режимі.

I added the applet, but it is shown without a shadow like the rest of the icons.

Well, if an applet (or more) doesn't have a shadow, you should either double-check that option All is set under Latte Settings -> Appearance.

What happens if I drag 'n' drop files on launchers?

The file will be passed as a parameter to the specific application, creating a new instance (e.g. passing an image to Kolourpaint will open the image with Kolourpaint).

Are there known compatibility issues with specific graphics drivers?

If you have Intel Graphics and experience problems with rendering such as pixelated graphics, corrupt text and others, you can try changing the 2D rendering method from SNA to UXA.

/etc/X11/xorg.conf.d/20-intel.conf

section     "Device"
Identifier  "Intel Graphics"
Driver      "intel"
Option      "AccelMethod"  "uxa"
EndSection

My dock doesn't show anymore when i activate the Auto-hide or the Dodge window feature

Apparently, some features from plasma can hinder Latte Dock's ability to show itself when touching the screen border. Plasma 5.10 added the option to execute actions on swiping over a border on a touch screen. You can find this option in System Settings under: Desktop behavior -> Touch screen. If you have your dock on the same border a touch gesture is active, the dock may not be able to show itself. Try deactivating the gesture on that border, then close and restart your session and check if the problem was fixed. (#676)
