The problem is that no matter the time I spent between steps 2 and 3, the BusyIndicator does not appear. The reason is, that your heavy-loading Loader is blocking the thread. Set it to asynchronous mode, to allow the rest of the program to run. Further, I'd recommend to prefer declarative bindings to imperative assignments in handlers. See my example:. Since the asynchronous Loader might display incomplete files for some time, I set it to be visible only when its status changes to ready.

Such as in Labview world I supposed that there was a place in this web-site where developer can share new graphic widgets which others can use in theirs user interface. I'm a fan of sharing code. Any way, thank you for your clarification. Therefore I have to start developing custom widget using QML. Do you have any advices to suggest to me to start programming widgets using QML, following the right way?
Well, I already gave you one link. You can also check www.Indicates background activity, for example, while content is being loaded. The busy indicator should be used to indicate activity while content is being loaded or the UI is blocked waiting for a resource to become available.

Due to the visual difference, busy indicators and indeterminate progress bars fit different places in user interfaces. Typical places for a busy indicator:.

Currently I use a GIF animation for that purpose. A very quick google search pointed me here: github. You should give them a try, or study how they did and write your own. I am aware of these projects, but my goal is to make my app simpler, and not to add another lines and 5 files. That is why I am interested in Qt's implementation.

When displaying progress for a sequence of processes, indicate overall progress rather than the progress of each activity. Progress indicators look and animate in ways that reflect the status of a process. They are never simply decorative.Tutorial Qt Creator - QML - StackView
Progress indicators use animation to capture Progress indicators should be applied to all instances of a process such as loading in a consistent format linear or circular. Material Design offers two visually distinct types of progress indicators: linear and circular progress indicators.
Only one type should represent each kind of activity in Only one type should represent each kind of activity in an app. Determinate indicators display how long a process will take. They should be used when the process completion rate can be detected. Indeterminate indicators express an unspecified amount of wait time.
As more information about a process becomes available, a progress indicator can switch from an indeterminate to a determinate state. The track is a fixed width rule, with set boundaries for the indicator to travel along. The indicator animates along the length of the track.
Linear progress indicators display progress by animating an indicator along the length of a fixed, visible track. The behavior of the indicator is dependent on The behavior of the indicator is dependent on whether the progress of a process is known. To indicate that loading affects the whole screen, a linear indicator can be placed in the background.
To focus user attention, a linear indicator is recommended for displaying item expansion onto larger surfaces, such as desktop. Circular progress indicators display progress by animating an indicator along an invisible circular track in a clockwise direction.
They can be applied directly to a They can be applied directly to a surface, such as a button or card. Circular progress indicators are positioned to indicate the process that they represent. Buttons allow users to take actions with a single tap. A circular indicator can be integrated into a button or actionable icon to express a connection between an interaction and a specific item.
They should be used for short, indeterminate activities between seconds. Longer activities may require alternate methods of communication, such as snackbars or notifications.
