Help with QFormLayout

Exotic_Devel

I do not want to prevent resizing, I just want to open the window like the image that is edited, however if the user resizes it he can. Once this window is called it appears as the original image, notice that the window is narrow and all the fields appear the same size, the field "Estado" will be entered only where the abbreviations of the states, SP, MG, RS, etc.. .. Is the same size of the field "Nome" that you may receive up to 50 characters, is disproportionate. To solve the problem of the size of the fields I used setMaximumWidth (int) to set the maximum size (width) of the QLineEdit, but do not know if this is the correct way.
What was I still could not make the open window as the size of the edited image. I edited the image resized with the mouse after it opened, but I want her to have open at that size. I've tried setSize setGeometry, without success.

Thanks for the help friend

You could use a combination of setminimumsizehint and a spacer for each row except the biggest one.

Like this (without the left part, to make my description simple):
Row 1 : hlayout : nome + lineedit (setminimumsizehint = 50)
Row 2 : hlayout :cep + linedi (setminimumsizehint = 15) + spacer
row 3 ....
.....

Did you have a look at the fieldGrowthPolicy property?

Actually what I need right now and set the initial window size. I'm trying to setGeometry, but ignores the window, perhaps because I'm using Layouts. I set the initial window size, but do not want to prevent the user can resize.
For QLineEdits QLabels and am using QFormLayout. Below is a picture showing how to structure my layouts.

What do you mean "ignores the window"? You should be able to set the geometry of the window, i.e. the widget that contains the top level layout. You should not use setGeometry on things inside a layout.

Of course, if the contents of the window does not allow the geometry you are setting it to, it will be as small/large is it can, but not exactly what you set it to.

I am using setGeometry in the class constructor. But nothing changes.

i've made a simple ui file for you to look into :
"link ":http://dl.dropbox.com/u/33544011/dialog.ui

I followed the principle using spacers

hope this helps.

Eddy, thanks for the example, but what I need now is to figure out how to set an initial size for the window.
I'm not using designer in this work, I am working on the arm.
I took a look at the code generated by the designer in the example you sent, but could not understand the code.

@class Ui_Dialog
{
public:
QGridLayout *gridLayout;
QListView *listView;
QVBoxLayout *verticalLayout;
QHBoxLayout *horizontalLayout;
QLabel *label;
QLineEdit *lineEdit;
QHBoxLayout *horizontalLayout_2;
QLabel *label_2;
QLineEdit *lineEdit_2;
QSpacerItem *horizontalSpacer;
QHBoxLayout *horizontalLayout_3;
QLabel *label_3;
QLineEdit *lineEdit_3;
QSpacerItem *horizontalSpacer_2;
QSpacerItem *verticalSpacer;

void setupUi(QDialog *Dialog)
{
    if (Dialog->objectName().isEmpty())
        Dialog->setObjectName(QString::fromUtf8("Dialog"));
    Dialog->resize(475, 129);
    gridLayout = new QGridLayout(Dialog);
    gridLayout->setSpacing(6);
    gridLayout->setContentsMargins(11, 11, 11, 11);
    gridLayout->setObjectName(QString::fromUtf8("gridLayout"));
    listView = new QListView(Dialog);
    listView->setObjectName(QString::fromUtf8("listView"));

    gridLayout->addWidget(listView, 0, 0, 1, 1);

    verticalLayout = new QVBoxLayout();
    verticalLayout->setSpacing(6);
    verticalLayout->setObjectName(QString::fromUtf8("verticalLayout"));
    horizontalLayout = new QHBoxLayout();
    horizontalLayout->setSpacing(6);
    horizontalLayout->setObjectName(QString::fromUtf8("horizontalLayout"));
    label = new QLabel(Dialog);
    label->setObjectName(QString::fromUtf8("label"));

    horizontalLayout->addWidget(label);

    lineEdit = new QLineEdit(Dialog);
    lineEdit->setObjectName(QString::fromUtf8("lineEdit"));
    lineEdit->setMinimumSize(QSize(0, 0));
    lineEdit->setMaximumSize(QSize(16777215, 16777215));

    horizontalLayout->addWidget(lineEdit);


    verticalLayout->addLayout(horizontalLayout);

    horizontalLayout_2 = new QHBoxLayout();
    horizontalLayout_2->setSpacing(6);
    horizontalLayout_2->setObjectName(QString::fromUtf8("horizontalLayout_2"));
    label_2 = new QLabel(Dialog);
    label_2->setObjectName(QString::fromUtf8("label_2"));

    horizontalLayout_2->addWidget(label_2);

    lineEdit_2 = new QLineEdit(Dialog);
    lineEdit_2->setObjectName(QString::fromUtf8("lineEdit_2"));
    lineEdit_2->setMinimumSize(QSize(0, 0));

    horizontalLayout_2->addWidget(lineEdit_2);

    horizontalSpacer = new QSpacerItem(40, 20, QSizePolicy::Expanding, QSizePolicy::Minimum);

    horizontalLayout_2->addItem(horizontalSpacer);


    verticalLayout->addLayout(horizontalLayout_2);

    horizontalLayout_3 = new QHBoxLayout();
    horizontalLayout_3->setSpacing(6);
    horizontalLayout_3->setObjectName(QString::fromUtf8("horizontalLayout_3"));
    label_3 = new QLabel(Dialog);
    label_3->setObjectName(QString::fromUtf8("label_3"));

    horizontalLayout_3->addWidget(label_3);

    lineEdit_3 = new QLineEdit(Dialog);
    lineEdit_3->setObjectName(QString::fromUtf8("lineEdit_3"));

    horizontalLayout_3->addWidget(lineEdit_3);

    horizontalSpacer_2 = new QSpacerItem(40, 20, QSizePolicy::Expanding, QSizePolicy::Minimum);

    horizontalLayout_3->addItem(horizontalSpacer_2);


    verticalLayout->addLayout(horizontalLayout_3);

    verticalSpacer = new QSpacerItem(20, 40, QSizePolicy::Minimum, QSizePolicy::Expanding);

    verticalLayout->addItem(verticalSpacer);


    gridLayout->addLayout(verticalLayout, 0, 1, 1, 1);

    gridLayout->setColumnStretch(1, 1);

    retranslateUi(Dialog);

    QMetaObject::connectSlotsByName(Dialog);
} // setupUi

};

namespace Ui {
class Dialog: public Ui_Dialog {};
} // namespace Ui@

The class Ui_Dialog does not use inheritance, and sets the window size in QDialog object passed as parameter.
The correct way would be to inherit from QDialog?:

class Ui_Dialog : public QDialog

and set the window size in the constructor, by calling a resize (x, y)?

I don't understand what you want. you say you don't want to use ui but you ask how to use it?

I you want to understand how to use the ui file, then you can simply use the wizard to create a new widget based project with QDialog and everything is set up for you. copy paste and you're done.
If you search the docs the principle is well explained there.

to control the size of your window you could use resize:
@int main(int argc, char *argv[])
{
QApplication a(argc, argv);
Dialog w;

w.resize(300,300);
w.show();

return a.exec&#40;&#41;;

}@

I did not ask how to use UI, I just tried to understand the code generated by the UI designer to be able to find the solution to my problem.
See my code up there is a class that inherits from QWidget and is displayed in a QMdiArea.

@void WindowMain::evoqueSubWindClientes()
{
QWidget *subwincli = new MdiChildClientes(this);
mdiarea->addSubWindow(subwincli);
subwincli->resize(800,600);
subwincli->show();
}@

But the command resize (800,600) does not have any effect.
