Note: This property applies to all TControl descendants. Set Alignment to determine whether the caption of the radio button should appear to the. To re-enable a control, set Enabled to True. Determines the position of the caption relative to the radio button. If Enabled is set to False, the control ignores mouse, keyboard, and timer events. Some disabled controls appear dimmed (for example: buttons, check boxes, labels), while others (container controls) simply lose their functionality without changing their appearance. To disable a control, set Enabled to False. Use Enabled to change the availability of the control to the user. If no Values strings are set, each button's caption serves as its value.Controls whether the control responds to mouse, keyboard, and timer events. Specify values for the buttons by editing the Values property in the Object Inspector the first string in Values corresponds to the first string in Items, and so forth. When the user selects a radio button, the "value" of the selected button becomes the contents of the linked field for the current record in the dataset. The TKeyEvent type points to a method that handles keyboard events. The OnKeyUp handler can respond to all keyboard keys, including function keys and keys combined with the Shift, Alt, and Ctrl keys. Each string in Items makes a radio button appear in the group box with the string as its caption. Description Use the OnKeyUp event handler to provide special processing that occurs when a key is released. Calling the Hide method sets it to false. Calling the Show method sets the control's Visible property to true. If Visible is false, the control is not visible. When the application is run the visual appearance of the buttons is erratic when the TListBoxItem is scrolled off the screen and back on. Use the Visible property to control the visibility of the control at runtime. On one of the TListBoxItems I have placed a number of TRadioButtons by simply dropping them on the TListBoxItem at design time. In TCustomRadioGroup descendants, where this property is published. 2 I am trying to implement a Firemonkey TListbox that has a number of TListBoxItems. But changing the DFM will not work for you. ![]() Usually, an OnChange event happens when the radio button state is changed. To add radio buttons to a TDBRadioGroup, edit the Items property in the Object Inspector. Items holds a TStrings object that lists the captions of the radio buttons in the group. 5,691 4 41 102 1 You changed the PAS, but not the DFM. Occurs when the state of TRadioButton is changed. They are also useful for displaying data from fields that have only a few possible values. to all public schools and learners, and can be ordered from Embarcadero Technologies. ![]() THtRadioButton HTML RadioButton - VCL TRadioButton descendant. Object Pascal (Delphi) for assessment in the NSC examinations. To add radio buttons to a TRadioGroup, edit the Items property in the Object Inspector. Supports basic properties and animation For Delphi XE+ uses VCL themes. Supports basic properties and animation THtCheckBox HTML CheckBox - VCL TCheckBox descendant. Database radio groups provide an easy way to ensure that the user enters one (or at most one) of the options presented for a field. THtLabel HTML Label - VCL TLabel descendant. Radio buttons that are contained directly in the same control component are said to be "grouped" when a radio button is checked, all other radio buttons in its group become unchecked. TRadioButton, also called option button, presents a set of mutually exclusive choices. ![]() Use TDBRadioGroup to group a set of data-aware radio buttons. TDBRadioGroup represents a group of radio buttons connected to a database. If the runtime themes disabled, the TRadioButton control is not transparent and its background is defined by its Color property.
