Managing Windows And Forms Dynamically

Dynamic Window and Form Handling

‘Hydra4GL’ allows the management of windows and forms dynamically. This gives the developer more control and increases efficiency as the code becomes more flexible and manageable. Functions with window operations can easily be written for code-reuse, which saves time and removes repetitive code fragments of window operations. All options and attributes available in the OPEN / CLOSE / CURRENT / CLEAR... Window/form statements are catered for and additional properties such as the Titlebar text can be managed too.

Relative Window positions

There is also the option to open windows absolute or relative to the parent window.
