The input dialog is in the Carbide.c++ designers's Notes and Dialogs section.



See this tutorial first in order to understand basics of creating and running an application: Helloworld tutorial

Step 1 - Start a new project

  1. Start with a new project using Carbide.c++ IDE.
  2. Call it dialogs ( or whatever you like).

Once you are done with all basic steps you will see this window.

Step 4 - Add event handler

  1. Add one menu item in the options menu.
    Refer to the above mentioned hello-world tutorial.
  2. Call this menu item as "Get Input".
  3. Now add an event handler to the menu item.

In the event handler the add the code for

  1. Show the dialog.
  2. Read the text from dialog.
  3. Show it back.

Step 5 - Generated Code

Notice that the IDE generated code for the function to show the data query dialog. Remember not to tamper with the code between the tags called "generated code" this may stop auto generation of code.

Step 6 - Executing the application

Now we are done with the code and design part. Run the application to text it in emulator and following should be the output.

Step 7 - Changing the properties

The properties of the dialog can be altered visually in GUI designer. Right click the dialog and then select "Show properties view" option.

This way we can develop the GUI based application using Carbide.C++ very quickly. Once the basic idea of using dialogs with the IDE is clear, one can go for other dialogs in the application.
