Detailed Description

Example of program using KeyboardTask

The following simple example demonstrates how to use the KeyboardTask controls.

Examples of usage:

#include "Toolkit/GUIToolkit.h"
 
int main ( int argc, char** argv )
{
    bool done = false;
 
    WidgetApplication *MyApp = new WidgetApplication();
    MyApp->setuniformbackgroundcolor(0, 0, 0);
 
    DesktopWidget *desktop1 = new DesktopWidget( (char*) "First Desktop", 0, 0, SCREEN_WIDTH, SCREEN_HEIGHT, nullptr );
 
    WindowWidget *window = new WindowWidget( (char*) "Examples of ButtonWidgets", 20, 30, 250, 160, desktop1 );
 
    ContainerVWidget *contH = new ContainerVWidget( (char*) "ContainerH", 1, 1, 1, 1, window );
 
    ButtonWidget *button = new ButtonWidget();          // Simple constructor so we need to assign all the parameters
 
    // First the label to be written on the button
    button->setlabel( (char*) "Enabled Button" );
 
    // then the dimensions (one by one in that case)
    button->setxpos( 5 );
    button->setypos( 10 );
    button->setwidth( 150 );
    button->setheight( 15 );
    // note : we can also use the method button->setdimensions( 5, 10, 150, 15 ) instead
 
    // and finally we assign the parent by adding the button as a child to conH
    contH->addchild( button );
 
    // This is a second button with all parameters passed through the constructon
    ButtonWidget *button2 = new ButtonWidget( (char*) "Disabled Button", 1, 1, 1, 1, contH );
    // We disable the button by using the inherited method Wigdet::disable()
    button2->disable();
 
    // the button to be clicked to quit
    ButtonWidget *buttonQuit = new ButtonWidget( (char*) "Quit [CTRL]+[ESC]", 1, 1, 1, 1, contH );
 
    // We ask for an automatic positioning of the widgets in the grid
    // Note : this will fully override the dimensions given to the Widgets manually
    window->adjust();
 
    MyApp->addchild( desktop1 );
 
    KeyboardTask *keyboard = MyApp->getkeyboardhandler();
 
    // We render the app for the first time so what we can see what's happening on the screen
    MyApp->render();
 
    while (!done)
    {
 
        MyApp->logic();
 
        if ((keyboard->kbCTRL && keyboard->kbESC) || buttonQuit->ispressed()) done = true;
 
    }
 
    return 0;
}

KeyboardTask class.

The class to be used for accessing the keyboard and keys information.

Examples of usage:

KeyboardTask* myKeys = new KeyboardTask(); // Simple constructor, will need specific properties assignement later

WidgetApplication myApp = new WidgetApplication();

KeyboardTask* myKeys = myApp->getkeyboardhandler();

Note: WidgetApplication creates a KeyboardTask object at initialisation. It is then better to ask for a direct access to its KeyboardTask by using the WidgetApplication::getkeyboardhandler() method.

See also: WidgetApplication::getkeyboardhandler()

Direct key status

Each key is defined by a boolean: true is the corresponding key is pressed and false overwise

Keynames are given as follows
