[solved] How to set the focus to a new widget dynamically added to the main Dialog ?
-
Hello,
I build a dialog box containing a custom widget which is added dynamically to the main dialog after clicked a push button. I would like that the new widget get the focus after it is added to the dialog box ? How to do it ? Thank
My code main dialogbox
@
QDlg::QDlg(const QStringList &Mnemos, QDialog* parent): QDialog(parent),m_Mnemos(Mnemos)
{
setCaption("Input");
setObjectName(QString("variantdiseasedlg"));
lpmainVboxLayout = new QVBoxLayout(this);
lpmainVboxLayout->setObjectName(QString("VerticalMainLayout"));lpWidgetVboxLayout = new QVBoxLayout(this);
qCustomWdg* lpCustomWdg = new qCustomWdg(1, 1, 0, m_Mnemos, this);
lpCustomWdg ->show();
lpWidgetVboxLayout->addWidget(lpCustomWdg );lpmainVboxLayout->addLayout(lpWidgetVboxLayout);
QHBoxLayout* lpButtonHboxLayout = new QHBoxLayout;
//lpButtonHboxLayout->setObjectName(QString("horizontalButtonLayout"));lpNewButton = new QPushButton(this);
lpNewButton ->setText("Add &new");
lpButtonHboxLayout->addWidget(lpNewButton );
QSpacerItem* lpSpacer = new QSpacerItem(100,20);
lpButtonHboxLayout->addItem(lpSpacer);QPushButton* lpRemoveButton = new QPushButton(this);
lpRemoveButton->setText("&Remove");
lpButtonHboxLayout->addWidget(lpRemoveButton);QPushButton* lpCancelButton = new QPushButton(this);
lpCancelButton->setText("&Cancel");
lpButtonHboxLayout->addWidget(lpCancelButton);QPushButton* lpOkButton = new QPushButton(this);
lpOkButton->setText("&Integrate");
lpButtonHboxLayout->addWidget(lpOkButton);lpmainVboxLayout->addLayout(lpButtonHboxLayout);
connect(lpNewButton ,SIGNAL(clicked()),this,SLOT(addNewWdg()));
connect(lpCancelButton,SIGNAL(clicked()),this,SLOT(reject()));
connect(lpOkButton,SIGNAL(clicked()),this,SLOT(accept()));m_newWdgList.append(lpCustomWdg );
}
@....
code adding the widget dynamically after pushing the "New" button.@void QDlg::addNewWdg()
{
if (! m_newWdgList.isEmpty())
{
//fill the custom widget with previous value;
qCustomWdg* lpLastWidget = m_newWdgList.last();
int iStartValue = lpLastWidget ->startValue();
int iEndValue = lpLastWidget ->endValue();
int iCurrentComboxIndex = lpLastWidget ->currentIndexComboBox();
lpCustomWdg = new qCustomWdg(iStartValue, iEndValue, iCurrentComboxIndex, m_Mnemos,this);}
else
lpCustomWdg = new qCustomWdg(1, 1, 0, m_Mnemos,this);m_newWdgList.append(lpCustomWdg );
lpWidgetVboxLayout->addWidget(lpCustomWdg );
lpCustomWdg ->show();
// I try this whithout effect , the focus stay on the main dialog box on the "New" push button
lpCustomWdg ->setFocusProxy(lpCustomWdg->lpLineEditPositionStart);}@
I suppose that may be the new custom widget can not get the focus because it is not completely build when I assign the focus ... but may be someone know how to solve this.
Thank for your help.

Hi, welcome to devnet
You seem to be setting focus proxy but not actually giving it a focus?
Try to call "setFocus()":http://qt-project.org/doc/qt-5/qwidget.html#setFocus on the lpCustomWdg. -
Hi,
Thank a lot, effectively giving the focus to the lpCustomWdg ( setfocus() ) and then setting focus proxy work properly !

Great, please prepend [Solved] to the title of the thread to let others know there's an answer here.

Ok, this work in Qt4, unfortenately same code doesn't make job in Qt3 ! In Qt3 setting the new CustomWdg isn't effective. Yes probably not a lot of people still using Qt3, but me I do !
-
Sorry, I can't help you with Qt3. I'm too young I guess ;)

Hi
So I'm looking for an old QT3 guru to solve my problem ;)
Thank you

Hi,
AFAIR, this should work the same, what OS are you running on ?
-
Yes it should ! working on ... XP and with vs2005...don't laught ! ;)

I post a solution :
I do not use setFocus() when using Qt3. After the addition of the new custom widget the focus goes (by magic) into the first QLineEdit of the new custom wdg.
Then I set the setTabOrder as follow :
@
setTabOrder(m_lpCustomWdg->lpCheckBoxLastWidgetOfTheCustom, lpNewButton);
setTabOrder(m_lpNewButton, m_lpRemoveButton);
setTabOrder(m_lpRemoveButton, m_lpCancelButton);
setTabOrder(m_lpCancelButton, m_lpOkButton);
@so code is : @void QDlg::addNewWdg()
{
if (! m_newWdgList.isEmpty())
{
//fill the custom widget with previous value;
qCustomWdg* lpLastWidget = m_newWdgList.last();
int iStartValue = lpLastWidget ->startValue();
int iEndValue = lpLastWidget ->endValue();
int iCurrentComboxIndex = lpLastWidget ->currentIndexComboBox();
lpCustomWdg = new qCustomWdg(iStartValue, iEndValue, iCurrentComboxIndex, m_Mnemos,this);}
else
lpCustomWdg = new qCustomWdg(1, 1, 0, m_Mnemos,this);m_newWdgList.append(lpCustomWdg );
lpWidgetVboxLayout->addWidget(lpCustomWdg );
lpCustomWdg ->show();
//if I do not make a setTabOrder after the last widget of the new custom wdg //the focus goes to the first new widget inserted.
setTabOrder(m_lpCustomWdg->lpCheckBoxLastWidgetOfTheCustom, lpNewButton);
setTabOrder(m_lpNewButton, m_lpRemoveButton);
setTabOrder(m_lpRemoveButton, m_lpCancelButton);
setTabOrder(m_lpCancelButton, m_lpOkButton);}@
A that's doing the job ! -
I won't had to work on that beast too ;)
Nice catch !
Since you found a solution, can you also please update the thread title prepending [solved] ? So other forums users may know :)
