The component allows dock the panels around the main window. You can undock the panel to float state and dock them back.The main window can be used as the QMainWindow, or, preferably Qtitan::DockMainWindow. Qtitan::DockMainWindow - already contains a configured dock panel manager. In the case of QMainWindow, you will need to create the dock panel manager manually.

Component implements the work with traditional ToolBars. Each tool bar dock side can have several rows for docking, and each row contains a set of ToolBars. When you move TooBar from one row to another within the same dock side, the mechanism either creates a new row or deletes it. This changes the size of the ToolBar. Automatic positioning is optimized so that when the dock side container is narrowed then ToolBar has the full size as long as possible which allows to observe all the commands on the ToolBar in contrast to the original Qt tool bar solution.

• Creating or adding the ToolBar to the container in the required position.
• Positioning the ToolBar side-by-side without overlapping.
• Dragging ToolBar between containers.
• Supports floating ToolBars.
• Supports multiple rows and columns in each dock side container when placing the ToolBar.
• Automatic calculation of the optimal ToolBar location when the dock side container is narrowed.
• Creating ToolBars on any QWidget.

You can save the state of the dock panels and tool bars into the XML file, and then restore it when a new session of the application is started. Or have several XML for different application profiles - as it implemented in Microsoft Visual Studio or other applications that support the docking panels feature.

Popular feature allows to quickly optimize the size of panels inside its containers to provide the end-user with the best overlook. This can be activated programmatically or by pressing a hot key.

Ability to deploy the dock panels or dock tool bars on any QWidget. To create you need to instantiate a docking manager and pass to the constructor of manager the QWidget on which you need to deploy the docking mechanism. All necessary infrastructure will be created automatically.

QtitanDocking component allows to hide and re-show panels and toolbars using the API or interactively, remembering the previous state. We carefully store the position and size of the panels, toolbars so that nothing gets lost when managing docking process.

Represents a container panel that contains other panels inside, enclosed into the tabs. Tabbed container it is a part of the docking layout. You do not need to create it manually; it is created automatically while working with the mechanism of docking panels.

Represents a container panel containing other panels inside, divided by a vertical or horizontal resizable splitter. Split container it is a part of the docking layout. You do not need to create it manually; it is created automatically while working with the mechanism of docking panels.

The container represents a special layout panel containing other panels and can hide behind the edge of the window, with the roll-out effect. Auto-Hide container it is a part of the docking layout. You do not need to create it manually; it is created automatically while working with the mechanism of docking panels.

The container represents a document layout panel which has its own dock sites, such as the top-level window. This container may contain a document panels or regular widget panels. There can be only one document layout panel on the top-level window.

If a end-user activates auto-hide mode for several widget panels in the same dock-site, then the panels are grouped into the tabs.

Panels are shown and hidden in the auto-hide mode using animation, as Microsoft Visual Studio does.

We tried to make the process of docking the panels and toolbars as convenient as possible. For these purposes, we will engage any input devices - mouse and keyboard.

To implement the process of window dragging for docking, we use the native operating system kernel commands like Visual Studio shell does. Most implementations on the market use the emulation based on intercepting the mouse move event when the window position is synchronized with the mouse position. This leads to lags in the process of dragging, the window seems to be late from the mouse. Also, a number of powerful functions that the operating system provides are not available. Our component use the best way:

• for MacOS - performWindowDragWithEvent
• for Linux - _NET_WM_MOVERESIZE event
• for Windows - system command SC_MOVE | 0x0002

Our docking component provides a great opportunity to add your own custom widgets or action buttons to the title bar of the dock panel or even add your own custom title bar widget to the dock panel.

QtitanDocking can work with or without a central widget. By default, the center widget is visible. If you don’t need it, just make it invisible through the property setVisible to false.

QtitanDocking was initially designed as a cross-platform component intended for desktop applications. The primary focus of development was on code quality and functionality. Docking system for now can be used for Windows and Mac OS. The component is well tested and targeted to work on 32 or 64 bit platforms as you wish.

The docking system is fully adapted for use in Python applications based on Qt PySide2. By default, Python version number 3.x is used. But Python bindings can be re-compilled for Python 2.7 too. Configuration scripts are reconfigured easily. They are made on the basis of QMake script.

Our docking component uses QStyle to draw primitives - a title bar of panels, markers, frames, tool-bar buttons and other elements. Therefore, it will look like a native in any custom style or in Qt default styles.

QtitanDocking component ships with the implementation of the Visual Studio 2019 style. This style supports three theme palettes - White, Dark, and Blue. The implementation of the style includes, in addition to drawing the elements that are required for the docking, painting the checkboxes, trees and grids, regular buttons, ribon bar buttons and others such as in the Visual Studio 2019. Your application will repeat the legendary Microsoft interface without any compomises!
