Hiding buttons when designing form and stopping form starting maximized

[Jimbo]

Hello,

Two questions regarding form development using QtDesigner.....

I would like to make a button hidden when the project is first run. I know how to do this in code but would like to set it up when creating the form. I have looked on the properties list for the button but can't see hide listed (only enabled)

Also, although my form is only small, whenever I run my program it starts maximized. I have tried changing the sizePolicy properties of the form but they don't seem to have an effect. How do I stop the form maximizing at startup?

Thanks for any guidance,

Jimbo

The property name is "visible", unfortunately it is not available in Qt Designer, as it is explicitly disabled in the Qt sources:

@
// from src/gui/kernel/qwidget.h:
Q_PROPERTY(bool visible READ isVisible WRITE setVisible DESIGNABLE false)
@

So, you're left to hide it in your C++ code, no better advice on this, sorry.

Regarding the maximized problem, this should normally not happen. Can you post a small, complete, compilabel example that demonstrates this?

Hi Volker,

Thanks for your help.

I'm not sure if you need all the files from my project or just the ui XML file. Here's that one:

With this standard implementation around the ui file everything works as expected:

addressbook.h
@

#ifndef ADDRESSBOOK_H
#define ADDRESSBOOK_H

#include <QWidget>

namespace Ui {
class AddressBook;
}

class AddressBook : public QWidget
{
Q_OBJECT

public:
explicit AddressBook(QWidget *parent = 0);
~AddressBook();

protected:
void changeEvent(QEvent *e);

private:
Ui::AddressBook *ui;
};

#endif // ADDRESSBOOK_H
@

addressbook.cpp
@

#include "addressbook.h"
#include "ui_addressbook.h"

AddressBook::AddressBook(QWidget *parent) :
QWidget(parent),
ui(new Ui::AddressBook)
{
ui->setupUi(this);
}

AddressBook::~AddressBook()
{
delete ui;
}

void AddressBook::changeEvent(QEvent *e)
{
QWidget::changeEvent(e);
switch (e->type()) {
case QEvent::LanguageChange:
ui->retranslateUi(this);
break;
default:
break;
}
}
@

main.cpp
@
#include <QtGui/QApplication>
#include "addressbook.h"

int main(int argc, char *argv[])
{
QApplication a(argc, argv);

AddressBook ab;
ab.show();

return a.exec();

}
