A TEdit is a control with a single line of editable text. It is available from the Standard tab of the Component Palette.

Usage

You can add to your form a TEdit input box add by clicking on it at the Standard component palette and place it on your form with one click. You can now edit this single-line text box at run time.

Want you this text elsewhere have, you can read this text, like every other String.

For example, you have a TEdit Edit1 on your form placed, you can use myString: = Edit1.Text;. To change the shown Text in Edit1, you can use Edit1.Text := myString;.

If you want to display another text instead of the default text (e.g. Edit1) in a TEdit Edit1 at the start of your application, you can proceed as follows:

• Select the TEdit on your form with one click.
• Go to the properties tab in the Object Inspector.
• Select the property Text and change it in the next input box.
• In the same way, you can select the property Name and give the TEdit a better name.

Password input

You can also easily use a TEdit to enter passwords. It is then instead of actually entered Char a PasswordChar displayed.

Little Example:

• Create a new GUI application with a TEdit Edit1 and a TButton Button1 on the form.
• In the Object Inspector set the property PasswordChar of Edit1 to a " * ".
• In the event handler of OnClick of Button1 show the entered password: ShowMessage(Edit1.Text);
