How to show and hide Button when i created.

[vudvpro]

- Create Layout:

void Schedule::createLayout()
{
	QVBoxLayout *mainLayout = new QVBoxLayout(); 
	QGridLayout *daysLayout = new QGridLayout();
	QWidget *viewport = new QWidget();
	mainLayout->addWidget(viewport);
 
	Token *label = new Token(this);
	label->setAlignment(Qt::AlignLeft);
	QList<Token *> cwList;
        cwList.append(label);
	daysLayout->addWidget(label);
 
 
	for (int i = 0; i < 5; i++ )
	{
		Button *label = new Button(this);
		label->setAlignment(Qt::AlignLeft);
		label->setOptimumSize(299, 15);
		label->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Fixed);
		SchedulesList.append(label);
		daysLayout->addWidget(label);
	}
 
	daysLayout->setSpacing(1);
	daysLayout->setContentsMargins(0,0,0,0);
	daysLayout->setAlignment(Qt::AlignCenter);
	viewport->setLayout(daysLayout);
 
	mainLayout->setSpacing(0);
	mainLayout->setContentsMargins(0,0,0,0);
	mainLayout->setAlignment(Qt::AlignCenter);
	setLayout(mainLayout);
}

void Schedule::createLayout()
{
	QVBoxLayout *mainLayout = new QVBoxLayout(); 
	QGridLayout *daysLayout = new QGridLayout();
	QWidget *viewport = new QWidget();
	mainLayout->addWidget(viewport);

	Token *label = new Token(this);
	label->setAlignment(Qt::AlignLeft);
	QList<Token *> cwList;
        cwList.append(label);
	daysLayout->addWidget(label);


	for (int i = 0; i < 5; i++ )
	{
		Button *label = new Button(this);
		label->setAlignment(Qt::AlignLeft);
		label->setOptimumSize(299, 15);
		label->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Fixed);
		SchedulesList.append(label);
		daysLayout->addWidget(label);
	}

	daysLayout->setSpacing(1);
	daysLayout->setContentsMargins(0,0,0,0);
	daysLayout->setAlignment(Qt::AlignCenter);
	viewport->setLayout(daysLayout);

	mainLayout->setSpacing(0);
	mainLayout->setContentsMargins(0,0,0,0);
	mainLayout->setAlignment(Qt::AlignCenter);
	setLayout(mainLayout);
}

- i want update layout can show and hide button.
i use:

QLayoutItem *Item = NULL;
for (int i = 0; i < 5; i++)
		{
			Item = daysLayout->itemAt(i);
			if (Item)
			{
				Item->widget()->hide();
				Item->widget()->adjustSize(); 
				Item->widget()->updateGeometry();
			}
		}
		daysLayout->update();

QLayoutItem *Item = NULL;
for (int i = 0; i < 5; i++)
		{
			Item = daysLayout->itemAt(i);
			if (Item)
			{
				Item->widget()->hide();
				Item->widget()->adjustSize(); 
				Item->widget()->updateGeometry();
			}
		}
		daysLayout->update();

But i can't show them again.

Where is the code for showing the buttons again?
You didn't post it.

This code Show:

std::vector<CScheduleItem*>::iterator it;
                QLayoutItem *Item = NULL;
	int i = 0;
	for (it = g_Gadget->GetPIMLookData()->m_vecShedules.begin(); it != g_Gadget->GetPIMLookData()->m_vecShedules.end(); it++)
	  {
                      Item = daysLayout->itemAt(i);
                      Item->widget()->show();
	  }

std::vector<CScheduleItem*>::iterator it;
                QLayoutItem *Item = NULL;
	int i = 0;
	for (it = g_Gadget->GetPIMLookData()->m_vecShedules.begin(); it != g_Gadget->GetPIMLookData()->m_vecShedules.end(); it++)
	  {
                      Item = daysLayout->itemAt(i);
                      Item->widget()->show();
	  }

Where is this code?
If you put a break point in the for loop, does it get caught?

Many thanks, My application worked.
- The first Create:

Token *label = new Token(this);
	label->setAlignment(Qt::AlignTop);
	label->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Fixed);
	cwList.append(label);
	daysLayout->addWidget(label);
 
	for (int i = 0; i < 5; i++)
	{
		Button *label = new Button(this);
		label->setAlignment(Qt::AlignTop);
		label->setOptimumSize(299, 15);
		label->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Fixed);
		SchedulesList.append(label);
		daysLayout->addWidget(label);
	}
	for (int i = 1; i < daysLayout->count(); i++)
	{
		daysLayout->itemAt(i)->widget()->hide();
	}

Token *label = new Token(this);
	label->setAlignment(Qt::AlignTop);
	label->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Fixed);
	cwList.append(label);
	daysLayout->addWidget(label);
	
	for (int i = 0; i < 5; i++)
	{
		Button *label = new Button(this);
		label->setAlignment(Qt::AlignTop);
		label->setOptimumSize(299, 15);
		label->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Fixed);
		SchedulesList.append(label);
		daysLayout->addWidget(label);
	}
	for (int i = 1; i < daysLayout->count(); i++)
	{
		daysLayout->itemAt(i)->widget()->hide();
	}

- After i show this:

int nCount = g_Gadget->GetPIMLookData()->m_vecShedules.size();
	std::vector<CScheduleItem*>::iterator it;
	int i = 0;
	int j = 1;
	//daysLayout->itemAt(0)->widget()->show();
	for (i; i < 5; i++)
	{		
		if (i < nCount)
		{
			if (!daysLayout->itemAt(i+1)->widget()->isVisible())
				daysLayout->itemAt(i+1)->widget()->show();
			j++;
		}
		if (j >= nCount+1 && i >= nCount)
		{
			if (daysLayout->itemAt(i+1)->widget()->isVisible())
				daysLayout->itemAt(i+1)->widget()->hide();
		}
		if (nCount == 0)
		{
			if (!daysLayout->itemAt(1)->widget()->isVisible())
				daysLayout->itemAt(1)->widget()->show();
		}
	}
	updateGeometry();
	if (g_Gadget->bRefresh == true)
		animateTop();

int nCount = g_Gadget->GetPIMLookData()->m_vecShedules.size();
	std::vector<CScheduleItem*>::iterator it;
	int i = 0;
	int j = 1;
	//daysLayout->itemAt(0)->widget()->show();
	for (i; i < 5; i++)
	{		
		if (i < nCount)
		{
			if (!daysLayout->itemAt(i+1)->widget()->isVisible())
				daysLayout->itemAt(i+1)->widget()->show();
			j++;
		}
		if (j >= nCount+1 && i >= nCount)
		{
			if (daysLayout->itemAt(i+1)->widget()->isVisible())
				daysLayout->itemAt(i+1)->widget()->hide();
		}
		if (nCount == 0)
		{
			if (!daysLayout->itemAt(1)->widget()->isVisible())
				daysLayout->itemAt(1)->widget()->show();
		}
	}
	updateGeometry();
	if (g_Gadget->bRefresh == true)
		animateTop();
