Qch file viewer

The text is used as the default text if no language attribute is specified. The text is taken from the file in the file tags. It is possible to specify a different file or any language. The icon defined by the icon tags is applied to any language. The copy is needed because Qt Assistant stores all its settings in the collection file; i. The directory is specified as a relative path. If the base attribute is set to "collection", the path is relative to the directory the collection file resides in.

If the attribute is set to "default" or if it is missing, the path is relative to the directory given by QDesktopServices::DataLocation. The first form is useful for collections that are used in a "mobile" way, e.

This functionality can be used while remote controlling Qt Assistant. To make it available for remote control set the tag value to true. QByteArray ba; ba. If the widget is already shown and this command is sent again, the widget will be activated, meaning that it will be raised and given the input focus. The URL can be absolute or relative to the currently displayed page.

If such an item has more than one link associated with it, a topic chooser will be shown. An ID is unique in each namespace and has only one link associated to it, so the topic chooser will never pop up. If depth is 0, the tree will be collapsed completely. If depth is -1, the tree will be expanded completely. This tag specifies which page should be display when pressing the home button in Qt Assistant 's main user interface.

This tag specifies which page Qt Assistant should initially display when the help collection is used. This tag specifies the filter that is initially used. This tag describes an icon that will be used instead of the normal Qt Assistant application icon. This tag is used to enable or disable user accessible filter functionality, making it possible to prevent the user from changing any filter when running Qt Assistant.

This tag is used to specify whether the documentation manager should be shown in the preferences dialog. This tag describes if the address bar can be shown. The aboutMenuText tag lists texts for different languages which will later appear in the Help menu; e. The aboutDialog tag can be used to specify the text for the About dialog that can be opened from the Help menu. This class provides a public function that is used to show pages of the documentation, and one private helper function to make sure that Qt Assistant is up and running.

Launching Qt Assistant is done in the function startAssistant by simply creating and starting a QProcess. If the process is already running, the function returns immediately.

Otherwise, the process has to be set up and started. To start the process we need the executable name of Qt Assistant as well as the command line arguments for running Qt Assistant in a customized mode.

The executable name is a little bit tricky since it depends on the platform, but fortunately it is only different on macOS. The displayed documentation can be altered using the -collectionFile command line argument when launching Qt Assistant. When started without any options, Qt Assistant displays a default set of documentation. When Qt is installed, the default documentation set in Qt Assistant contains the Qt reference documentation as well as the tools that come with Qt, such as Qt Designer and qmake.

In our example, we replace the default documentation set with our custom documentation by passing our application-specific collection file to the process's command line options. As the last argument, we add -enableRemoteControl , which makes Qt Assistant listen to its stdin channel for commands, such as those to display a certain page in the documentation. Then we start the process and wait until it is actually running. If, for some reason Qt Assistant cannot be started, startAssistant will return false.

The implementation for showDocumentation is now straightforward. Firstly, we ensure that Qt Assistant is running, then we send the request to display the page via the stdin channel of the process. It is very important here that the command is terminated by an end of line token to flush the channel.

Finally, we make sure that Qt Assistant is terminated properly in the case that the application is shut down. The destructor of QProcess kills the process, meaning that the application has no possibility to do things like save user settings, which would result in corrupted settings files.

To avoid this, we ask Qt Assistant to terminate in the destructor of the Assistant class. The MainWindow class provides the main application window with two menus: the File menu lets the user open and view an existing file, while the Help menu provides information about the application and about Qt, and lets the user open Qt Assistant to display the application's documentation.

To be able to access the help functionality, we initialize the Assistant object in the MainWindow 's constructor. Then we create all the actions for the Simple Text Viewer application. This action is connected to the showDocumentation slot of the MainWindow class.

Add comment. Accounting, financial and tax file type. The qch file extension is associated with the Quicken , a personal finance management tool developed by Intuit, Inc, which is available in both Windows and Mac Versions. This qch file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types like documents, projects etc. Quicken is personal finance management program for Windows that comes in several editions: Quicken Deluxe, Quicken Premier, Quicken Starter. Hint: Click on the tab below to simply browse between the application actions, to quickly get a list of recommended software, which is able to perform the specified software action, such as opening, editing or converting qch files.

Here you can also create your own entry with the. QCH extension if there is no such in the registry. All available options are listed in the context menu right mouse button or in the "Edit" menu after placing the cursor in the appropriate place on the screen.
