OBT File – What is .obt file and how to open it?

OBT File Definition and Purpose

An OBT file is an Openbox Theme File, a configuration file employed by Openbox, a lightweight and configurable window manager for the X window system primarily used in Linux-based operating systems. Openbox is a minimalist window manager that focuses on efficiency and customization, and OBT files play a crucial role in defining the visual appearance and behavior of Openbox desktop environments.

OBT files contain various settings that determine the appearance of the desktop, including the window borders, titlebars, menus, and icons. They can be used to modify the colors, fonts, and images used in the Openbox environment, allowing users to create personalized and visually appealing desktops. OBT files also store settings for window behavior, such as the size, position, and behavior of windows, providing users with granular control over the functionality of their desktop. Additionally, OBT files can be shared among users, enabling the easy exchange of custom desktop configurations.

Opening OBT Files with Openbox

Openbox, a lightweight and customizable window manager for X11-based desktop environments, uses .OBT (Openbox Theme File) files to define the graphical appearance of its interface elements. To open an OBT file, users must have Openbox installed on their system. Once installed, users can follow these steps:

1. Open the Openbox configuration menu by right-clicking on the desktop and selecting “Openbox Configuration.”
2. Navigate to the “Theme” tab in the configuration menu.
3. Click on the “Import” button and select the desired OBT file.

Upon importing the OBT file, Openbox will automatically apply the theme to its interface elements, such as the window borders, title bars, and menus. Users can customize the theme further by editing its settings in the “Theme” tab.

Alternative Methods for Opening OBT Files

In addition to using Openbox, there are other methods for opening OBT files:

• Text Editor: OBT files are plain text files that can be opened and viewed using any text editor, such as Notepad or TextEdit. However, editing OBT files in a text editor is not recommended, as it can disrupt the theme’s functionality.
• OBT Viewer Apps: Several third-party applications allow users to view and edit OBT files. These apps typically provide a graphical user interface for managing themes and making customizations. One popular OBT viewer app is OBConf (Openbox Configuration Interface), which can be used to create, edit, and manage Openbox themes.

Definition and Usage

An Openbox Theme File (OBT) is a file used in the Openbox window manager. It defines the visual appearance of the window decorations such as the titlebar, borders, and buttons. An OBT file contains a set of rules and options that specify the colors, textures, and shapes of these elements. It is a plaintext file written in an XML-like format.

Structure and Contents

An OBT file typically begins with an XML declaration and a root element called <theme>. Within the <theme> element, there are multiple sections that define different aspects of the theme. These sections include <titlebar>, <border>, <button>, <font> (for text appearance), and <include> (for importing other OBT files). Each section contains one or more <style> elements that specify the properties of the corresponding element. Styles are defined using key-value pairs, where the key represents an attribute and the value represents its value.

Installation and Customization

OBT files are typically installed in the ~/.themes directory. After installation, the theme can be activated from the Openbox configuration manager or by editing the ~/.config/openbox/rc.xml file. OBT files can be customized by editing them directly or using graphical theme editors such as Obconf or Theme Wizard. Customization options include changing colors, gradients, textures, and layout. By editing the OBT file, users can create custom themes that match their personal preferences and enhance the visual appeal of their Openbox desktop environment.
