Greetings,
I am working on creating a customised extended Ext::Panel and I am getting
errors when I run (it compiles fine) my code and start a session. The
constructor of the sub class is below:-
When the session fails depending on how i comment certain blocks out I get
either a "*Segmentation fault*" error or *"assert failed" *in the WContainer
class (I believe its somewhere within the setimplementation block that takes
a layout item).
Am I doing something incorrect or out of sequence? Could you please assist
and help me correct this?
I am aware of the
*"...This layout manager is applicable only to WContainerWidget container
widgets. You may use it within an Ext::Container indirectly by first setting
a WContainerWidget using a WFitLayout."*
note from the documentation but I am not sure if this may be a reason since
I try to indirectly assign the layout to the Ext::Panel. There seems to be
an issue with layout managers and Ext::Panels.
Thanks in advance.

//initialiser for class that descends from Ext::Panel
MyPanel::MyPanel():Ext::Panel(){
// I create textboxes and button here; connect signals
resize(WLength(6,WLength::Inch),WLength(7,WLength::Inch));
uname=new WLineEdit();
uname->setTextSize(10);
uname->setMaxLength(10);
pword=new WLineEdit();
pword->setTextSize(10);
pword->setMaxLength(10);
pword->setEchoMode(WLineEdit::Password);
WLabel* ulabel=new WLabel("Username");
ulabel->setBuddy(uname);
WLabel* plabel=new WLabel("Password");
plabel->setBuddy(pword);
Button* b=new Button ("OK");
b->setDefault(true);
b->clicked.connect(SLOT(this, MyPanel::LoginUser));
LoginResult.connect(SLOT(this, MyPanel::Success));
//set default layout of panel to WBorderLayout
layout=new Wt::WBorderLayout();
setLayout(layout);
//create 2 top to bottom box layouts
WBoxLayout* top =new WBoxLayout(WBoxLayout::TopToBottom);
WBoxLayout* center =new WBoxLayout(WBoxLayout::TopToBottom);
//added 2 box layouts to container widgets
WContainerWidget* centerwid=new WContainerWidget();
WContainerWidget* topwid=new WContainerWidget();
centerwid->setLayout(center);
topwid->setLayout(top);
//put gui elements on center widget
centerwid->layout()->addWidget(ulabel);
centerwid->layout()->addWidget(uname);
centerwid->layout()->addWidget(plabel);
centerwid->layout()->addWidget(pword);
centerwid->layout()->addWidget(b);
//finally, added 2 top to bottom widgets to border layout of this
class
layout->addWidget(topwid, WBorderLayout::North);
layout->addWidget(centerwid, WBorderLayout::Center);
}
