A slider allows the user to
set a value on a continuous range of possible values, such as
volume control, or the speed of a movie being shown. Sliders are
useful when the exact value is less important than its position
relative to the range of possible values.
You can create a slider:
·
|
In the Definer, by using the Slider display type for a
domain. |
·
|
In the Windows Designer, by inserting a slider control class
into a window or dialog. |
If you create the control
using the Slider display type, allowed values must be defined at
domain level. In this case, the slider appears automatically after
synchronization.
If you create the control in
the Windows Designer, allowed values can either be hard-coded, or
retrieved from the database by means of a SQL statement or Related
Column.
To insert a slider:
1.
|
Use the Windows Designer catalog to open the appropriate
window/dialog. |
2.
|
In the design view, select the object into which you want to
insert a slider. |
3.
|
From the menu bar, choose Insert, Slider, or drag your own
slider control class from the Controls tab page of the Windows
Designer catalog. |
4.
|
Select the slider, and then open the Property Inspector. |
5.
|
On the General tab page of the Property Inspector: |
·
|
Set the Range Maximum, and Range Minimum properties to indicate
the range of allowed values. |
·
|
Set the Prompt property. |
6.
|
On the Visual tab page of the Property Inspector: |
·
|
Set the Tick Mark Position property to indicate whether the
tick marks must be displayed at the top or at the bottom of the
slider. |
·
|
Set the Tick Mark Frequency property to indicate how many tick
marks the slider is to have (for example, if you type "5", every
fifth unit will have a tick mark). |
