dxInputBox(string,string,string) Method

Displays a modal input dialog box that prompts a user to confirm the displayed text string or change it.

Declaration

function dxInputBox(const ACaption: string; const APrompt: string; const ADefaultValue: string): string;

Parameters

Name	Type	Description
ACaption	string	The caption of the invoked input dialog box.
APrompt	string	The label of the displayed text editor.
ADefaultValue	string	The default value displayed in the text editor.

Returns

Type	Description
string	The editor value.

Remarks

Call the dxInputBox function to display a simple input dialog box that prompts a user to confirm or modify the display text string. The dialog box imports all look & feel settings from the TdxSkinController component if it is in an application project.

Code Example: Create a Simple Input Dialog Box

The following code example creates a simple modal input dialog box with predefined text:

Delphi

uses
  dxInputDialogs;  // Declares the dxInputBox function
// ...

var
  AUserInput: string;
begin
  AUserInput := dxInputBox('Add a New User', 'User name:', 'User1');
  // ...
end;

C++

#include "dxInputDialogs.hpp"  // Declares the dxInputBox function
// ...

  UnicodeString AUserInput;
  // ...
  AUserInput = dxInputBox("Add a New User", "User name:", "User1");
  // ...

Note

If you need to display password characters instead of actual user input, prepend an ASCII character whose number is less than 32 (for example, #31 in Delphi or /x31 in C++Builder) to the value passed as the APrompt parameter.

Displayed password characters depend on the current global look & feel settings. If the native style is enabled, a modal input dialog box displays bullets as password characters. Otherwise, the dialog box displays asterisks.
