Hi,
I am working on simple layout app.
Currently the app has one layout with a button and two edit boxes and a bunch of labels.
Practically it is the logIn page for the app.
I am trying to create an onFocus event where one of the labels disappear when the user clicks on the box to enter its username.
You can see it on one f the uploaded pictures.
On a click event I calling a function where setting the content of the label empty string. However I keep getting the following error messages. the labels name is 'usernameBox'
main.cpp
C:\MyApps\SProject\main.cpp(16) : error C2065: 'usernameBox' : undeclared identifier
C:\MyApps\SProject\main.cpp(16) : error C3861: 'SetLabel': identifier not found
SProject: 1 file(s) built in (0:03.16), 3167 msecs / file, duration = 3167 msecs, parallelization 0%
There were errors. (0:03.27)
And here how my code looks like
.h file
#ifndef _SProject_SProject_h
#define _SProject_SProject_h
#include <CtrlLib/CtrlLib.h>
using namespace Upp;
#define LAYOUTFILE <SProject/SProject.lay>
#include <CtrlCore/lay.h>
class SProject : public WithSProjectLayout<TopWindow> {
public:
void HideBoxText();
typedef SProject CLASSNAME;
SProject();
};
#endif
.cpp file
#include "SProject.h"
SProject::SProject()
{
CtrlLayout(*this, "Window title");
Sizeable().Zoomable();
logInButton <<= THISBACK(HideBoxText);
}
void HideBoxText(){
usernameBox.SetLabel("");
}
GUI_APP_MAIN
{
SProject().Run();
}
.lay file
LAYOUT(SProjectLayout, 704, 524)
ITEM(Button, logInButton, SetLabel(t_("LogInButton\aLogIn")).SetFont(StdFontZ(18).Bold().Italic()).SetFrame(FieldFrame()).LeftPosZ(304, 104).TopPosZ(420, 32))
ITEM(EditField, LogInTxtBox, MaxChars(18).SetFont(StdFontZ(14)).SetFrame(FieldFrame()).WantFocus(false).LeftPosZ(268, 168).TopPosZ(292, 28))
ITEM(Label, usernameBox, SetLabel(t_("\"UsernameBoxLabel\aUsername ")).SetFont(StdFontZ(12).Italic()).LeftPosZ(268, 164).TopPosZ(296, 21))
ITEM(StaticText, dv___3, SetText(t_("Restaurant’s Easy One Solution")).SetFont(SansSerifZ(20).Bold()).LeftPosZ(192, 332).TopPosZ(104, 36))
ITEM(StaticText, dv___4, SetText(t_("Welcome")).SetAlign(ALIGN_CENTER).SetFont(SansSerifZ(20).Bold()).LeftPosZ(184, 332).TopPosZ(64, 19))
ITEM(StaticText, dv___5, SetText(t_("to")).SetAlign(ALIGN_CENTER).SetFont(SansSerifZ(20).Bold()).LeftPosZ(332, 40).TopPosZ(84, 19))
ITEM(EditField, dv___6, SetFrame(FieldFrame()).WantFocus(false).LeftPosZ(268, 168).TopPosZ(324, 27))
ITEM(Label, passwordBox, SetLabel(t_("Password")).SetFont(StdFontZ(12).Italic()).LeftPosZ(268, 125).TopPosZ(328, 21))
END_LAYOUT
Also how I set the name of the label you can see it in the
Any help will be greatly appreciated.

Hi,
Here is you problem:| nejnadusho wrote on Mon, 15 October 2012 05:49 |
void HideBoxText(){
usernameBox.SetLabel("");
}
|
The HideBoxText is a global function, and usernameBox is a variable in SProject classs. You just forgot the "SProject::" 
Best regards,
Honza
