Newbie problem opening form based on resource identifier

[dunff2k]

Hey guys, newbie question...

I have created a simple form in the rss file and created a class that extends CAknForm and am now looking to launch it.

So in the Application Gui class (HandleCommandL()) I've included the following code that is executed given a certain option selection in the menubar.

// my created form, ignore the parameters
CMyForm* form = CMyForm::NewL(iAppView->iDisplayText,iAppView->iTextColor);

// open form based on entry in resources file
form->ExecuteLD(r_SimpleEx_form);

however on compilation im told that the the "identifier r_SimpleEx_form cannot be found"

I tried to 'include' the rss file in this class but at compilation im told the file cannot be opened?

Below is the corresponding entry in the rss file which compiles file, (I've exluded some of the things this points to for clarity)

RESOURCE FORM r_SimpleEx_form
	{
	flags = EEikFormEditModeOnly | EEikFormUseDoubleSpacedFormat;
	items = 
	  {
	   DLG_LINE
		   {
		   type=EEikCtEdwin;
		   prompt="Text";
		   id=ESimpleExText;
		   control=EDWIN{width=10;maxlength=256;};
		   },
	   DLG_LINE
           {
           type=EAknCtPopupFieldText;
           prompt="Color";
           id=ESimpleExPopup;
          //itemflags = EikDlgItemTakesEnterKey | EEikDlgItemOfferAllHotKeys;
           control = POPUP_FIELD_TEXT
        	   {
        	    popupfield = POPUP_FIELD
        	    	{
        	    	width = 10;
        	    	};
        	    textarray=r_color_list;
        	   };
           }
	  };
        
	
	}

Any ideas why I can't refer to the above resources entry? Should the rss file be an include? if so any ideas why it can't be opened?

Hi,
Include #include <your rss name.rsg> in your corresponding cpp file and
declare your code like
form->ExecuteLD(R_SIMPLEX_FORM); you can check this resource id in your rsg file. It will compile then.

Resource basics: resource identifiers are converted to full uppercase, and defined in the .rsg file for your resource file (it is generated if the HEADER keyword is present in the START RESOURCE - END block in the .mmp).
Form basics: you need a DIALOG resource for launching a form.
Note that your SDK may already contain form-related documentation, check if there is s60_platform_avkon_ui_resources_forms_vx_y_en.pdf in S60Doc folder).

thanks for the response chaps,

now I get the message:

"illegal access from 'CMyForm' to protected/private member 'CAknDialog::ExecuteLD(int)"

Any ideas?

Hi,
Try inheriting your class something like
"class CMyForm : public CAknDialog" (by default it is private access scope)

[dunff2k]

Ok so before the inheritence was down as:

class CMyForm : CAknForm

which I changed to:

class CMyForm : public CAknForm

now I get lots of unidentified symbol compilation errors, mainly to do with CCoeControl and CEikDialog

e.g.

Undefined symbol: 'void CEikDialog::SetSizeAndPosition(class TSize const
(?SetSizeAndPosition@CEikDialog@@MAEXABVTSize@@@Z)'

Undefined symbol: 'class CCoeControl * CEikDialog::ComponentControl(int) const (?ComponentControl@CEikDialog@@MBEPAVCCoeControl@@H@Z)'

what does this mean?

thanks for your attention

[wizard_hu_]

Both error messages mention a method from CEikDialog. So check the necessary libraries for CEikDialog in the SDK Help, and make sure that they are added to your project.

[dunff2k]

ok i hunted down the library and all works fine, thanks!

If anyone else is interested the library I was missing was

eikdlg.lib (CEikDialg class)

use this not as an include but use the LIBRARY keyword in the mmp file

LIBRARY eikdlg.lib

Hi,

Try adding eikdlg.lib library in your mmp sth like
LIBRARY eikdlg.lib
