• Force: Click (check) this box to force the Tag Database to recognize a tag change when the user clicks on
the object, even if the value of the tag in question does not change.
• Enable Focus: When this option is checked, the object can receive the focus during runtime by the
navigation keys.
• Push Like: When this option is checked the control is displayed as a button, instead of the standard
check box standard shape.
• Fill Color: Specify the fill color for the button. This option is enabled only when the Push Like option is
checked.
• Auto Format: When checked, if the caption includes a decimal value enclosed by curly brackets (e,g,
{1.2345}) or a tag of Real type (see Caption above), then the value will be formatted according to the
virtual table created by the SetDecimalPoints function.
Modes of Operation
The Check Box object can operate in two different modes: Normal and Tri-State. For more information, see
Modes of operation for Check Box and Radio Button objects.
RADIO BUTTON OBJECT
The radio button object is useful to create interfaces where the users can chose one option from multiple
options on the display.
On the Graphics tab, in the Active Objects group, click Radio Button to create a radio button object on your screen:
1. Click in the drawing area and drag the mouse/cursor to draw the radio button and its label.
2. Release the mouse button when the object is the size you want.
3. Double-click on the object to view the Object Properties dialog.
Object Properties: Radio Button
Tip: To change the default size of the radio button, edit your project file (project_name.app) to add
the following setting:
[Objects]
RadioButtonSize=height_in_pixels
Doing this will change the size of all radio buttons in your project.
Use the Object Properties dialog to specify the following parameters for the radio button object:
• Caption: Specify a caption by typing the text into the text box. You can include a tag by enclosing it in curly
brackets (e.g., {tagname}).
• Fonts: Specify a font style for the caption by clicking the Fonts button.
• E-Sign: When this option is checked, the user will be prompted to enter the Electronic Signature before
executing the command.
• Confirm checkbox: Click (check) this box to ensure IWS prompts you to confirm the action at runtime.
• Key drop-down list: Select a key from the list to associate that keyboard key with the object or group of
objects. You can then press this key to check/uncheck the radio button.
