Example 3.38. Register the button handler for button5
MyWindow::MyWindow(Void) : SFRTitleWindow(SFRApplication::GetInstance(),
SFXRectangle(20, 20, 200, 250), "my window") static_throws
{
// register drawing handler

}
// register key handler
if (static_try()) {

}
// create buttons

SFRButtonControlPtr button5 = new SFRButtonControl(this,
SFXRectangle(70, 45, 50, 25),

// register handler for when button1 is pressed
if (static_try()) {

HANDLER_FUNCTION(OnButtonControl1)));
}
// register handler for when button2 is pressed
if (static_try()) {

}
// register handler for when button3 is pressed
if (static_try()) {
static_throw(
button3->RegisterHandler(SREVT_CONTROL,

HANDLER_FUNCTION(OnButtonControl3)));
}
// register handler for when button4 is pressed
if (static_try()) {
static_throw(
button4->RegisterHandler(SREVT_CONTROL,
HANDLER_BEFORE,
HANDLER_FUNCTION(OnButtonControl4)));
}
// register handler for when button5 is pressed
if (static_try()) {
static_throw(
button5->RegisterHandler(SREVT_CONTROL,
HANDLER_BEFORE,
HANDLER_FUNCTION(OnButtonControl5)));
}
// create checkboxes
_checkbox1 = new SFRCheckboxControl(this,
SFXRectangle(10, 115, 90, 20),
"check1");
_checkbox2 = new SFRCheckboxControl(this,
SFXRectangle(105, 115, 90, 20),

// create radiobuttons
_radiobutton1 = new SFRRadiobuttonControl(this,
SFXRectangle(10, 140, 90, 20),
"radio1");
_radiobutton2 = new SFRRadiobuttonControl(this,
SFXRectangle(105, 140, 90, 20),
"radio2");
// group together radiobuttons
_radiobutton2->Group(_radiobutton1);
// set radiobutton1 to selected status
_radiobutton1->SetStatusCheck(true);
// create combobox
SFXWideString item[] = {"item1", "item2", "item3"};
_combobox = new SFRComboboxControl(this,
SFXRectangle(10, 165, 90, 20),
item,
lengthof(item));
// register handler for when combobox item is selected
if (static_try()) {
static_throw(
_combobox->RegisterHandler(SREVT_CONTROL,
HANDLER_BEFORE,
HANDLER_FUNCTION(OnComboboxControl)));
}
// create editbox control
// "hello textbox" is displayed by default setting
_editbox = new SFREditboxControl(this,
SFXRectangle(10, 190, 150, 28),
"hello textbox");
// set maximum size for input
_editbox->SetMaxSize(255);
// register handler when text has been entered,
// or when focused is moved
if (static_try()) {
static_throw(
_editbox->RegisterHandler(SREVT_CONTROL,
HANDLER_BEFORE,
HANDLER_FUNCTION(OnEditboxControl)));
}
// change into input mode when "Select" key is pressed
// while edit control is focused
// (SelectHandler is handler for "Select" key event)
if (static_try()) {
static_throw(
RegisterHandler(SFEVT_KEY,
AVK_SELECT,
HANDLER_AFTER,
HANDLER_FUNCTION(SelectHandler)));
}
}
Example 3.39. Implement the button handler for button5
// Button handler ( this handler is executed when "button5" is pressed) HANDLER_IMPLEMENT_VOIDCONTROL(MyWindow, OnButtonControl5, result, control) { // structure for parameter to create multidialog SFRMultiDialog::ParamRec param; // text to be displayed in multidialog param.text = "Finish application?"; // label for first button param.ok = "ok"; // label for second button param.cancel = "no"; // label for third button (null text: no button) param.another = ""; // initial setting of focus position param.focus = SFRMultiDialog::FOCUS_OK; // image icon param.image = SFBImageSmp(null); // create multidialog SFRMultiDialogPtr multiDialog = new SFRMultiDialog( SFXRectangle(10, 40, 220, 140), "Finish?", param); // register dialog handler if (static_try()) { static_throw( multiDialog->RegisterHandler( SREVT_DIALOG, HANDLER_BEFORE, HANDLER_FUNCTION(OnDialog))); } }
Example 3.40. Declare the multidialog handler
SFMTYPEDEFCLASS(MyWindow)
class MyWindow : public SFRTitleWindow {
SFMSEALCOPY(MyWindow)
public:
MyWindow(Void) static_throws;
virtual ~MyWindow(Void);
// *** added code segments are in bold
private:
// defined as member variables (type: pointer)
SFRCheckboxControlPtr _checkbox1;
SFRCheckboxControlPtr _checkbox2;
SFRRadiobuttonControlPtr _radiobutton1;
SFRRadiobuttonControlPtr _radiobutton2;
SFRComboboxControlPtr _combobox;
SFREditboxControlPtr _editbox;
HANDLER_DECLARE_VOIDRENDER(OnRenderContent)
HANDLER_DECLARE_BOOLEVENT(OnKey)
HANDLER_DECLARE_VOIDCONTROL(OnButtonControl1)
HANDLER_DECLARE_VOIDCONTROL(OnButtonControl2)
HANDLER_DECLARE_VOIDCONTROL(OnButtonControl3)
HANDLER_DECLARE_VOIDCONTROL(OnButtonControl4)
HANDLER_DECLARE_VOIDCONTROL(OnButtonControl5)
HANDLER_DECLARE_VOIDCONTROL(OnEditboxControl)
HANDLER_DECLARE_VOIDDIALOG(OnDialog)
};
Example 3.41. Implement the multidialog handler
// Multidialog handler ( this handler is executed when "ok" or "no" are pressed in multidialog ) HANDLER_IMPLEMENT_VOIDDIALOG(MyWindow, OnDialog, result, dialog) { switch(result) { case SRP16_OK: // when "ok" is pressed TRACE("OK"); // terminate application SFRApplication::Terminate(); break; case SRP16_CANCEL: // when "no" is pressed TRACE("CANCEL"); // close dialog dialog->DialogHandler(); break; } }
Customize the class which inherits from SFRFrameDialog. Register the key and drawing handler in the same way as the Window class.
Example 3.42. Define the dialog
SFMTYPEDEFCLASS(MyDialog)
class MyDialog : public SFRFrameDialog {
SFMSEALCOPY(MyDialog)
public:
MyDialog(Void) static_throws;
virtual ~MyDialog(Void);
HANDLER_DECLARE_VOIDRENDER(OnRenderContent)
HANDLER_DECLARE_BOOLEVENT(OnKey)
};
In the constructor, register the key and drawing handlers for dialog.
Example 3.43. Implement the dialog
// Constructor MyDialog::MyDialog() : SFRFrameDialog(SFXRectangle(10, 40, 220, 80)) static_throws { if (static_try()) { static_throw( RegisterHandler(SREVT_RESPONDER_RENDER, SRP16_RENDER_CONTENT, HANDLER_BEFORE, HANDLER_FUNCTION(OnRenderContent))); } if (static_try()) { static_throw( RegisterHandler(SFEVT_KEY, HANDLER_AFTER, HANDLER_FUNCTION(OnKey))); } } // Destructor MyDialog::~MyDialog(Void) { return; } // Drawing handler HANDLER_IMPLEMENT_VOIDRENDER(MyDialog, OnRenderContent, graphics) { graphics->FillRectangle(GetContentWorld(), SFXRGBColor(0xCC, 0xFF, 0xFF, 0x00)); graphics->DrawString( "when 3 key is pressed, close", SFXRectangle(10, 10, 200, 80), SFXRGBColor(0, 0, 0, 0), IDF_ALIGN_LEFT | IDF_ALIGN_MIDDLE); } // Key handler HANDLER_IMPLEMENT_BOOLEVENT(MyDialog, OnKey, event) { switch (event.GetP16()) { case AVK_3: // when "3" key is pressed // close return Invoke( SFXEvent(SREVT_RESPONDER_TERMINATE, SRP16_TERMINATE_INVOKE, true)); } return false; }
Extend the key handler to display the dialog when the "2" key is pressed.
Example 3.44. Key handler for HelloWorld : dialog is displayed when the "2" key is pressed
// Key handler HANDLER_IMPLEMENT_BOOLEVENT(MyWindow, OnKey, event) { switch (event.GetP16()) { ... // *** add the codes below case AVK_2: if (static_try()) { MyDialogPtr dialog; // create dialog with new operator if ((dialog = new MyDialog()) != null) { // rest of the code is for error handling static_throw(*dialog); if (!static_try()) { delete dialog; } } else { static_throw(SFERR_NO_MEMORY); } } return true; } return false; }
