In previous examples, we already use .Items several times (see Getting Started with DelphiVCL III: Overview of Commonly used VCL Components). We use it in ListBox, ComboBox, and RadioGroup. Items contain the strings that appear in the ListBox, ComboBox, and RadioGroup.
Use Items to add, insert, delete and move items. By default, the items in a list box are of type Strings. Use this item type to access its methods or properties to manipulate the items in the list.
Here is the working example of the implementation of .Items in the list box:
|
1 2 3 4 5 6 7 8 |
# Items in list box lboxCountry = ListBox(pgOne) lboxCountry.SetProps(Parent=pgOne) lboxCountry.SetBounds(145,88,121,60) lboxCountry.Items.Add('RUSSIA') lboxCountry.Items.Add('USA') lboxCountry.Items.Add('INDIA') lboxCountry.Items.Add('AUSTRALIA') |
The result:
Here is the working example of the implementation of .Items in combo box:
|
1 2 3 4 5 6 7 8 |
# Combo box cbxCity = ComboBox(pgOne) cbxCity.SetProps(Parent=pgOne,Name='ComboBox') cbxCity.SetBounds(145,206,121,60) cbxCity.Items.Add('New York') cbxCity.Items.Add('Sydney') cbxCity.Items.Add('Banglore') cbxCity.Items.Add('Tokyo') |
The result:
Here is the working example of the implementation of .Items in radio group:
|
1 2 3 4 5 6 |
# Radio group Creation rbgRadioBox = RadioGroup(pgOne) rbgRadioBox.SetProps(Parent=pgOne,Caption='Gender') rbgRadioBox.SetBounds(20,250,242,90) rbgRadioBox.Items.Add('Male') rbgRadioBox.Items.Add('Female') |
The result:
