Adding email functionality in QtreeWidget--Urgent reply needed
-
I am trying to make an organization browser. I am suppose to add a functionality that makes possible to send email by right clicking on the name. There should be an option that displays send email after right click. Then the email client should open after it. I dont know where to right the code for it. Do I need to make a separate class. Below is my code: till now in the .cpp file. Also help in what to include in the header file.
#include "dialog.h"
#include "ui_dialog.h"
#include <QtCore>
#include <QtGui>
#include <QTreeWidgetItem>
#include <iostream>
#include <QLabel>
#include <QDesktopServices>Dialog::Dialog(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::Dialog)
{
ui->setupUi(this);ui->treeWidget->setColumnCount(6); ui->treeWidget->setColumnWidth(0,200); ui->treeWidget->setColumnWidth(1,200); ui->treeWidget->setColumnWidth(2,200); ui->treeWidget->setColumnWidth(3,200); ui->treeWidget->setColumnWidth(4,200); ui->treeWidget->setColumnWidth(5,200); ui->treeWidget->setHeaderLabels(QStringList() << "CDSID" <<"First Name"<< "Last Name" <<"Role"<< "Reports To" << "Cube"); AddRoot("Organization Browser","\0","\0", "\0", "\0","\0");
}
void Dialog::AddRoot( QString CDSID, QString Fname, QString Lname, QString Role, QString ReportsTo, QString Cube)
{
QTreeWidgetItem *itm = new QTreeWidgetItem(ui->treeWidget);
QTreeWidgetItem *itm1 = new QTreeWidgetItem();itm->setText(0,CDSID); itm->setText(1,Fname); itm->setText(2,Lname); itm->setText(3,Role); itm->setText(4,ReportsTo); itm->setText(5,Cube); ui->treeWidget->addTopLevelItem(itm); AddChild(itm,"JOSTROW7","x","x", "v", "c","d"); AddChild(itm1,"CDSID","First Name","Last Name", "Role", "Reports To","Cube");
}
void Dialog::AddChild(QTreeWidgetItem *parent, QString CDSID, QString Fname, QString Lname, QString Role, QString ReportsTo, QString Cube)
{
QTreeWidgetItem *itm = new QTreeWidgetItem();
itm->setText(0,CDSID);
itm->setText(1,Fname);
itm->setText(2,Lname);
itm->setText(3,Role);
itm->setText(4,ReportsTo);
itm->setText(5,Cube);
parent->addChild(itm);// Reports to Jeff(All are Supervisors)
QTreeWidgetItem *k_itm=new QTreeWidgetItem(itm,QStringList() <<"3"<<"9"<<"9"<<"2"<<"1"<<"D701\n");

void Dialog::on_pushButton_clicked()
{
QLabel label("<a href='mailto:someone@somewhere.com'>email someone</a>");
label.setOpenExternalLinks(true);
label.show();QLabel label("<a href='mailto:someone@somewhere.com'>email someone</a>"); label.connect(&label, &QLabel::linkActivated, [](const QString &link) { QDesktopServices:openUrl(QUrl(link)); }); label.show();
}
Dialog::~Dialog()
{
delete ui ;
} -
Hi and welcome
Its not clear what part is not working.
However, i noted the following:
You are creating the QLabel as local variable.
It will not survive after on_pushButton_clicked() ends so
is that what you intend?void Dialog::on_pushButton_clicked()
{
QLabel label("<a href='mailto:someone@somewhere.com'>email someone</a>");
label.setOpenExternalLinks(true);
label.show();
..
}Also , i think you can just use
http://doc.qt.io/qt-5/qdesktopservices.html
for it.
"If a mailto URL is specified, the user's e-mail client will be used to open a composer window containing the options specified in the URL, similar to the way mailto links are handled by a Web browser." -
I have another problem with respect to sending more than one emails.
I can select multiple rows via mouse or keyboard from the tree, but when I click send email, it sends only to the currentItem. I tried to use selecteditems, but in vain. Below is how the code looks for the email part. I think some function is missing that allows me to send the emails to all the selected Items. Note: data(0,0) is the first column that has the email addresses.QString strTo = "mailto:";
strTo.append(ui->treeWidget->currentItem()->data(0,0).toString());openUrl->openUrl(QUrl(strTo));

Hi
- I tried to use selecteditems, but in vain.
something like ?
void SendMail(QString email) {
QString strTo = "mailto:";
strTo.append(email);
openUrl->openUrl(QUrl(strTo));
}QList<QTreeWidgetItem *> itemList;
itemList = this->MyTree->selectedItems();
foreach(QTreeWidgetItem *item, itemList)
{
QString str = item->data(0,0).toString());
SendEmail(str);
} -
Thanks for the reply. It worked. Lastly I need to add some more functionality. I added check boxed to each item. Now If I check the root I need all the items to be checked. If I select a child all the subchilds of it should be checked. Moreover, after clicking the send email, it should send the email to all the checked boxes. Also, I dont need the selection feature (I need only checked feature)
Below is the code I am struggling with:void Dialog::on_pushButton_clicked() { //Send Email QList<QTreeWidgetItem *> itemList; itemList = ui->treeWidget->selectedItems(); QString strTo = "mailto:"; foreach(QTreeWidgetItem *item, itemList) { // if(item->text(0)=="Organization") // continue; if(item->checkState(0)== Qt::Checked) { strTo.append(item->text(0)+";"); } } openUrl->openUrl(QUrl(strTo)); }

Hi
Ok checked is not the same as selected so- itemList = ui->treeWidget->selectedItems();
is not really what u want as that is selected not checked so unless they are ALSO selected
the list is empty.You can use
http://doc.qt.io/qt-5/qtreewidgetitemiterator.html#detailsTo process all checked items.
Alternatively this is also possible:
http://stackoverflow.com/questions/9986231/getting-a-qtreewidgetitem-list-again-from-qtreewidgetdoStuffWithEveryItemInMyTree( tree->invisibleRootItem() ); void doStuffWithEveryItemInMyTree( QTreeWidgetItem *item ) { // Do something with item ... for( int i = 0; i < item->childCount(); ++i ) doStuffWithEveryItemInMyTree( item->child(i) ); }

QStringList getCheckedAdresses(const QAbstractItemModel* model, const QModelIndex& parent = QModelIndex()){ QStringList result; if(!model) return result; if(parent.isValid()){ if(parent.model()!=model) return result; } for(int i=0;i<model->rowCount(parent );++i){ for(int j=0;j<model->columnCount(parent );++j){ const QModelIndex currIdx=model->index(i,j,parent); if(currIdx.data(Qt::CheckStateRole).toInt()) result.append(currIdx.data().toString()); if(model->hasChildren(currIdx)) result.append(getCheckedAdresses(model,currIdx)); } } return result; }
then use it in
const QStringList adresses = getCheckedAdresses(ui->treeWidget->model()); if(!adresses.isEmpty()) openUrl->openUrl(QUrl("mailto:"+adresses.join(';')));
-
Okay. I am totally lost. Below is my complete code. So anyone please give me the exact solution according to my scenario. That will be a great help.
Please note: I want 3 functionalities.
-
If I check the parent node, all the children under get be checked. Later when I click send email, the email be sent to all the checked ones.
-
If I check a child node, any subchild under it be checked. Later when I click send email, the email be sent to all the checked ones.
-
If I check a child node, that does not have any child, only it should be checked. Later when I click send email, the email be sent to all the checked ones.
Also, I have made lined between different items. There are four levels.
- Org (Clicking this will select all)
2) Senior Manager (Clicking this will select all managers only)
3) Manager (Clicking this will select all employees under him)
4) Employee (Clicking this will select only him)

Later when I click send email, the email be sent to all the checked ones.
put my
getCheckedAdresses
function from above somewhere in your code (a private member of Dialog or just pasting it at the top of the .cpp file, after the includes)then delete everything in
Dialog::on_pushButton_clicked
and pasteconst QStringList adresses = getCheckedAdresses(ui->treeWidget->model()); if(!adresses.isEmpty()) openUrl->openUrl(QUrl("mailto:"+adresses.join(';')));
for the parent-checks-the-child I don't think it's that straightforward, you'll probably have to store the check state twice in two roles then when
dataChange
signal is emitted formui->treeWidget->model()
you have to check if the 2 check roles match and if they don't then the check canged and you should check the cildren. All this becauseQStandrdItemModel
, which runs under the hood ofQTreeWidget
, sends always an empty vector as third argument ofdataChange
. I hope some of the ginuses roaming around here have a better solution -
The program is getting crashed when I click the send email button.
There should be some solution. I think I am missing some functions. Hope somebody replies soon with the solution. -
Still it is getting crashed. I guess there should be some other way.
-
You could debug it ? ;)
place a breakpoint in the slot for the Send Email
button and single step from there.That should give us the exact line where it crashes and hopefully also why it crashes :)

Okay. I am still unable to do. However, in the .ui file, I found a way that we can just drag n drop a treewidget and add the items. I just need to do one thing now. i.e iteration and send emails to the checked ones. The items can be accessed by ui->treeWidget. I can send emails to the selected ones by:
void MainWindow::on_pushButton_clicked()
{
//Send EmailQList<QTreeWidgetItem *> itemList; itemList = ui->treeWidget->selectedItems(); QString strTo = "mailto:"; foreach(QTreeWidgetItem *item, itemList) { if(item->checkState(0)== Qt::Checked) strTo.append(item->text(0)+";");
}
{ ui->treeWidget->;} openUrl->openUrl(QUrl(strTo));
}
But I dont want the selection functionality. I only want checked functionality. That means, if an item is checked, email will be send to it.
Please provide the code for the iteration of items in the treewidget (iteration of all, parents and child). -
Hi @VRonin already gave you the code in
https://forum.qt.io/topic/71237/adding-email-functionality-in-qtreewidget-urgent-reply-needed/7You cannot use selectedItems(); since you want the Checked ones.
You need to do it recursively as @VRonin shows.
for(int i=0;i<model->rowCount(parent );++i){
....
if(model->hasChildren(currIdx)) ...
result.append(getCheckedAdresses(model,currIdx)); <<<<< here it calls itself again. So it processes its children too, and its children and its children and..
.... -
@mrjj said in Adding email functionality in QtreeWidget--Urgent reply needed:
if(model->hasChildren(currIdx)) ...
I did it in other way. Simple and easy.
QString strTo = "mailto:";
QTreeWidgetItemIterator item(ui->treeWidget);
while (*item) {
if ((*item)->checkState(0) == Qt::Checked)
strTo.append((*item)->text(0)+";");
++item;
}
openUrl->openUrl(QUrl(strTo)); -

super. -
Ouch. One more functionality needed to be added. I request all my folks to please assist me in this as well.
Now I need to get the data from the SharePoint site. So what can be the code in Qt that can get the data from SharePoint and work in the same manner. So, in other words, it will get the data from SharePoint, and display all the data from it. Then whatever is checked from the tree will be included with the "mailto:" string.
So basically, no hard coding but getting the data from Sharepoint.
Pleae let mek now. -
Hi
- get the data from the SharePoint site
From rest service ?
From SQL server ?
From ?
What data ?
Unless the SharePoint devs knows 100% what you mean, i doubt
there be many answer :)
Maybe I just dont know SharePoint well enough :) - get the data from the SharePoint site
-
I am linking the sharepoint data with an access file. Now I need to connect the access file with the Qt application that I made. So I need the code to connect to the access file, read the data from there and display it.. Also let me know where to write the code. In the header file, main.cpp, mainwindow.cpp or somewhere else.
