key events

[manzoor10]

Okay I managed to get key events from OfferKeyEventL function. There is a lack in it, in that when I press 2 key it gets 2 only not 'a', 'b' or 'c'. How to get that?

Here's my code for OfferKeyEventL function

TKeyResponse CtestGuiAppView::OfferKeyEventL(const TKeyEvent& aKeyEvent,
												TEventCode aType)
	{
	
	if (aType != EEventKey)
		return EKeyWasNotConsumed;
	
	if (aKeyEvent.iCode == EKeyEnter)
		{
		return EKeyWasConsumed;
		}
	else
		{
		inputBuf.Append(aKeyEvent.iCode);
		DrawNow();
		return EKeyWasConsumed;
		}
	}

The Draw function is implemented as

void CtestGuiAppView::Draw(const TRect& /*aRect*/) const
	{
	// Get the standard graphics context
	CWindowGc& gc = SystemGc();

	// Gets the control's extent
	TRect drawRect(Rect());
	
	// Clears the screen
	gc.Clear(drawRect);
	const CFont* font = CEikonEnv::Static()->TitleFont();
	gc.UseFont(font);
	gc.SetPenColor(KRgbBlack);
	TPoint pos(50, 50);
	gc.DrawText(inputBuf, pos);
	
	}

One thing else I want is that when the end of line is reached (on screen) it starts printing on the next line (on screen) any hints?

And how does the code draws text next to the previous character. I mean how does it changes it position the pos is at 50,50.

for getting the FEP input without focusing input control, you should use CPTiEngine: http://wiki.forum.nokia.com/index.ph...guage_variants

And for the line questions, I quess you need to do your own logic for it. For drawing, just add stuff into buffer and drae the buffer, so you don't need to handle separate characters, and for end of space in the screen, you could check CFont fucntions for checking buffer lenght in pixels.

anyway, would it be easier to use Editors and let them handle all issues.

and what do you mean by editors in symbian? are there such classes? if so which ones? I might research on them

and what do you mean by without focusing? Isn't there a simpler way?

like in a console program using Getch we can get the other characters.

Anyting that is derived from CEikEdwin would do file, you could also search Wiki, check examples from the example section, as well as see SDK examples, they all have editor examples available.

You gotta have a focus on the editor, or it will not get any key input, see any example with more than one components in it for more information.

In general console applications end up being more difficult than GUIs, so you would be better by starting with GUI applciations.

OK here is my try...

void CtestGuiAppView::ConstructL(const TRect& aRect)
	{
	// Create a window for this application view
	CreateWindowL();
	
	// Instantiate the control
	iInputBox = new (ELeave)CEikEdwin;
	iInputBox->SetContainerWindowL(*this);
	
	// Create a resource reader
	TResourceReader reader;
	iCoeEnv->CreateResourceReaderLC(reader, R_INPUTBOX);
	iInputBox->ConstructFromResourceL(reader);
	CleanupStack::PopAndDestroy();
	iInputBox->SetFocus(ETrue);

	// Set the windows size
	SetRect(aRect);

	// Activate the window, which makes it ready to be drawn
	ActivateL();
	}

where iInputBox is a *CEikEdwin.

the resource

RESOURCE EDWIN r_inputbox
	{
	maxlength = 511;
	flags = EEikEdwinWidthInPixels;
	avkon_flags = EAknEditorFlagNoT9;
	default_case = EAknEditorLowerCase;
	allowed_case_modes = EAknEditorUpperCase | EAknEditorLowerCase;
	allowed_input_modes = EAknEditorTextInputMode | EAknEditorNumericInputMode;
	default_input_mode = EAknEditorTextInputMode;
	special_character_table = R_AVKON_SPECIAL_CHARACTER_TABLE_DIALOG;
	}

here's my OfferKeyEventL function

TKeyResponse CtestGuiAppView::OfferKeyEventL(const TKeyEvent& aKeyEvent,
												TEventCode aType)
	{
	if (iInputBox)
		{
		return iInputBox->OfferKeyEventL(aKeyEvent, aType);
		}
	else
		{
		return CCoeControl::OfferKeyEventL(aKeyEvent, aType);
		}
	}

It is causing panic EIKON-EDWIN 5

looks rather alike : http://wiki.forum.nokia.com/index.ph...in_Text_Editor, but not actually the same, so maybe you could try copying the wiki example directly, or have a look into bigger example at: http://www.forum.nokia.com/info/sw.n...r_Example.html

[manzoor10]

It is the same, actually it is

http://wiki.forum.nokia.com/index.php/Plain_text_editor

[symbianyucca]

Actually it is not the same, the link I gave has slightly different implementation..

[manzoor10]

Lol it is just a one line of code... alright

here is it

	// Instantiate the control
	iInputBox = new (ELeave)CEikEdwin;
	iInputBox->SetContainerWindowL(*this);
	
	// Create a resource reader
	TResourceReader reader;
	iCoeEnv->CreateResourceReaderLC(reader, R_INPUTBOX);
	iInputBox->ConstructFromResourceL(reader);
	CleanupStack::PopAndDestroy();

it is in the ConstructL of View class

RESOURCE EDWIN r_inputbox
{
	maxlength = 511;
	default_case = EAknEditorTextCase;
	allowed_case_modes = EAknEditorAllCaseModes;
	numeric_keymap = EAknEditorStandardNumberModeKeymap;
	default_input_mode = EAknEditorTextInputMode;
	allowed_input_modes = EAknEditorAllInputModes;
	special_character_table = R_AVKON_SPECIAL_CHARACTER_TABLE_DIALOG;
}

the resource file..

Anyway, if it is still not working, you could try one without resource definitions: http://wiki.forum.nokia.com/index.php/Editor_example

[manzoor10]

I want to know why that code is not working and the features in that class are excessive for requirement.
