layout warning from designer for custom plugin
Message 1 in thread
Hi,
I have designed a custom plugin which contains two tables arranged
vertically. The custom plugin is working as designed.The problem here is
when ever I add this plugin on to a dialog in a designer I keep getting
this message when I save the dialog.
"No entry for 0x87705d8 (mainLayout, QVBoxLayout) found in MetaDataBase"
and I keep on getting this message when I run the program which uses
this plugin and the dialog was designed in the designer using the
custom plugin.
"QLayout "testdiamondtableLayout" added to QgtDiamondTable
"testdiamondtable", which already has a layout"
With out a layout in the plugin for the tables the table doesn't get
displayed in a dialog.
Should I use the parents layout ?
Let say I am using the parents, then there may be a chance that the
parent is not yet layouted during designing.
below is a small piece of code for the Custom plugin and there one
layout intialized in the custom plugin which is done in this constructor.
QgtDiamondTable::
QgtDiamondTable(QWidget *parent ,
const char *name,
int pnumColumns ): QWidget( parent, name ),
spreadshtname( name )
{
mainlayout = new QVBoxLayout( this );
mainlayout->setMargin( 0 );
variableTable =new QTable( this , ( spreadshtname + "var" ) );
variableTable->hide();
variableTable->setLeftMargin( 0 );
variableTable->setTopMargin( 0 );
variableTable->setSizePolicy( preferred );
//set the table
mainTable = new CustomTable( this , spreadshtname );
mainTable->hide();
mainTable->setLeftMargin( 0 );
mainTable->setTopMargin( 0 );
mainTable->setSelectionMode( QTable::SingleRow );
mainTable->setFocusStyle( QTable::FollowStyle );
mainTable->setShowGrid( false );
//mainTable->setSizePolicy(expand);
Initialize();
Draw();
//add table to the layout
mainlayout->addWidget( variableTable );
mainlayout->addWidget( mainTable );
connect( mainTable, SIGNAL( clicked (int, int , int , const
QPoint&) ),
this, SLOT(loadRowToEdit() ));
variableTable->show();
mainTable->show();
Draw( );
} // spread sheet ends here
