New page

A radio button is a widget that only works together in a group of two or more radio buttons. Inside this group of radio buttons, only one button can be checked at a time. When you click on another raido button, the current one gets disabled and the new one becomes gets the checked state.

== API reference ==
The API reference for the radio button widget can be found [http://ugfx.org/images/resources/doxygen/master/group___radio_button.html here].

== Example ==
The following example shows how to use the radio button widget. In this example we create two groups where each group consists of three radio buttons:
<syntaxhighlight lang=c>
#include "gfx.h"

#define GROUP1 0 // this will be the first radio button group
#define GROUP2 1 // this will be the second radio button group

static GListener gl;
static GHandle ghRadio11, ghRadio12, ghRadio13; // the first group
static GHandle ghRadio21, ghRadio22, ghRadio23; // the second group

static void createWidgets(void) {
GWidgetInit wi;

// Apply some default values for GWIN
wi.customDraw = 0;
wi.customParam = 0;
wi.customStyle = 0;
wi.g.show = TRUE;

// create Radio11
wi.g.y = 10; wi.g.x = 10; wi.g.width = 80; wi.g.height = 20; wi.text = "Radio 1";
ghRadio11 = gwinRadioCreate(NULL, &wi, GROUP1);

// create Radio12
wi.g.y = 50; wi.g.x = 10; wi.g.width = 80; wi.g.height = 20; wi.text = "Radio 2";
ghRadio12 = gwinRadioCreate(NULL, &wi, GROUP1);

// create Radio13
wi.g.y = 90; wi.g.x = 10; wi.g.width = 80; wi.g.height = 20; wi.text = "Radio 3";
ghRadio13 = gwinRadioCreate(NULL, &wi, GROUP1);

// create Radio21
wi.g.y = 10; wi.g.x = 120; wi.g.width = 80; wi.g.height = 20; wi.text = "Radio 1";
ghRadio21 = gwinRadioCreate(NULL, &wi, GROUP2);

// create Radio22
wi.g.y = 50; wi.g.x = 120; wi.g.width = 80; wi.g.height = 20; wi.text = "Radio 2";
ghRadio22 = gwinRadioCreate(NULL, &wi, GROUP2);

// create Radio23
wi.g.y = 90; wi.g.x = 120; wi.g.width = 80; wi.g.height = 20; wi.text = "Radio 3";
ghRadio23 = gwinRadioCreate(NULL, &wi, GROUP2);

// Check the first radio buttons
gwinRadioPress(ghRadio11);
gwinRadioPress(ghRadio21);
}

int main(void) {
GEvent* pe;

// Initialize the display
gfxInit();

// Set the widget defaults
gwinSetDefaultFont(gdispOpenFont("UI2"));
gwinSetDefaultStyle(&WhiteWidgetStyle, FALSE);
gdispClear(White);

// Attach the mouse input
gwinAttachMouse(0);

// create the widget
createWidgets();

// We want to listen for widget events
geventListenerInit(&gl);
gwinAttachListener(&gl);

while(1) {
// Get an Event
pe = geventEventWait(&gl, TIME_INFINITE);

switch(pe->type) {
case GEVENT_GWIN_RADIO:
printf("group: %u radio: %s\n", ((GEventGWinRadio *)pe)->group,
gwinGetText(((GEventGWinRadio *)pe)->radio)
);
break;

default:
break;
}
}

return 0;
}
</syntaxhighlight>
