Level Control Property Dialog

The elements of a Level control are as follows:

Color Properties

All of the color properties below use a common set of controls similar to the following:

When the Use Theme is configured, which is the default, Halogen uses the current page theme color.

When Custom is configured, Halogen uses the color shown in the color chooser. To select a new custom color, click on the color chooser drop-down arrow and scroll the list to find the color that you desire to use, then click on it.

The number beside the color in the color chooser is a unique reference number for that color to help you set the custom color to a specific color, perhaps matching a custom color that you've selected for a page element.

The color reset button resets the custom color to the current theme color and changes the selection to Use Theme.

Layout Properties

All of the layout properties below use a common set of controls similar to the following:

As you change the page element's position or size, the layout properties change to reflect the current settings.

You can also change position or size by entering new values directly into the Layout property text boxes.

note: Some page elements do not support resizing in both dimensions. In this case, the layout properties area shows all of the settings (X, Y, W, and H), but disables those you cannot change. For example, the HAL system sets a Selector control's height according to the number of selections in the active link. Because of this, the control page designer disables the H text box for the control.

The reset button resets Height and Width to the defaults for the page element's selected Size.

UI Element	Purpose
Name	This is the name of the external control, which is the same as the name in the Control Page Designer palette. To change the name, enter a new value in the text box.
Layout	The top left (X,Y) position and Height and Width of the Level control.
Size	A drop down menu which selects the overall size of the level control as it appears on the control page.
Level: Orientation	Select the orientation of the level control on the control page using the drop down menu. A level control can be either vertical (default) or horizontal.
Level: Elements	Use this to choose the elements of the level control that appear on the control page. When Buttons is checked, Halogen includes the Up and Down buttons. When Slider is checked, Halogen includes the slider portion of the level control. When Value is checked, the value number (0 - 100%) appears in the control. note: You must select at least one of the elements: the property dialog prevents you from unchecking all three boxes.
Level: Value color	This is the color setting for the level control's Value number.
Level: Background color	This is the color setting for the level control's Background.
Label: Layout	The top left (X,Y) position and height and width of the level control's Label.
Label: Show	Check this box to show the level control's Label on the control page. Uncheck it to hide the Label.
Label: Text	This is the text of the level control's Label on the control page. It is the same as the Label of the external control. To change the Label, enter a new value in the text box.
Label: Text color	This is the color setting for the level control Label text.
Label: Style	Select style attributes for all of the text in the control's Label to be normal or any combination of bold, italic, and underlined.
Label: Alignment	The first set of three buttons allows horizontal alignment of the control's Label text to the left, center, or right of the label box. The second set of three buttons allows vertical alignment of the label's text to the top, center, or bottom of the label box.
Layering	All elements on a control page can overlap each other and are layered according to the order that you added them to the page. If you'd like to adjust the order so that this element appears either behind or in front of the other elements it overlaps, use these controls. To move the element to the top of the order, so that it is in front of all other elements on the page, click the icon. To move the element to the bottom of the order, so that it is behind all other elements on the page, click the icon.
Enable	This checkbox enables or disables the control on the control page. When a control is enabled, it is fully operational on the page and the user can change the control's value. When disabled, the control appears grayed out (dim) and the user can see the control's value but cannot change it. This enable control is the same as the Enable for the external control and you can link it to another toggle control in the Halogen configuration to control the enable state when the system is operating.
