Toolbox Progress-bar
A Progress-bar control in an InForm application presents the user with a visual indication of the progress of an on-going task. This page provides more detailed information about Progress-bar controls.
Progress-bar control
Create a new Progress-bar control by clicking the Progress-bar icon 
in the Toolbox. The newly created control will be displayed in the preview window; allowing you to move it around to meet your design requirements. Edit the Progress-bar properties as necessary.
10) Progress-bar Properties:
Progress-bar example: Preview window.
Note:Progress-bar properties will reflect the highlighted control selected in the preview window, enabling you to customize it as needed.
A ProgressBar control presents the user with a visual indication of the progress of an ongoing task.
Set its Min and Max properties at design time. Update the ProgressBar Value property at runtime.
If you set its ShowPercentage property to True, you can have the control's Caption property show in the bar's area.
You embed the actual percentage by using the placeholder \#.
Progress-bar example
Specification: Let the progress-bar example have the following design specification:
- Let the progress have a range of 0-10.
- Add two buttons to increment and decrement the progress bar.
- A set button forces the progress bar to 50%.
- Add a Track/Bar slider to increment and decrement the progress bar.
Implimenation: The following provide solutions for the above:
- Set the MIN and MAX properties to 0 and 10, respectively.
- Button hover uses the subroutine __UI_MouseEnter.
- Up, Down, Set, TrackBar, and ProgressBar use the subroutine __UI_Click.
- For additional details, check out Progress_Tracker_example.bas.
- At the layout stage, save the project using File -> Save project as and enter the name Progress_Tracker_example.
