How to access objects of parent Dialog from Child Dialog .

imrrk

if we look at std phone calendar,onfirstclick they just show the date,but if we again click the date ,a dialog is opened and we are asked to set reminders,I am asking u that kind of mechanism..

So, that means that you only do something with a click, if that date is already the selected date. Well... you have access to the selected date, so I suggest you use it.

ok can u show me by a small code snippet..it will be very helpful

hey whether i should use selectedDate function..?

imrrk

hello friends,I have a doubt,Now when i click on any date in calendar widget,I have written slot so as to show the date in a textbrowser as shown in code below
@void Dialog::on_Date_Clicked(QDate date)
{
ui->TextBrowser->setText(date.toString());

}@
Now again when i click on selected date I want to open a newdialog
so on first click it shows the date in browser and on secondclick it should open a dialog..
so how should i proceed..

Create a state machine and handle it there :-)

if you need different actions on the same signals, reconnect to different slot, have some state variables, whatever.

Well, one way might be to compare the current content of the text browser with the string representation of the date that was clicked. If they match, then you open the dialog, if they don't, you only set the textual representation of the date in the text browser. Or one of the many, many other ways (most of them better structured than this one) you can do this.

imrrk, this is reall, really basic programming. I would recommend you do some kind of basic programming course, or at least get yourself a good book on the topic at beginners level.

hey i know andre,and i can do it,but in I am not understanding it in qt framework,so I asked it..

imrrk

hey gerolf,I connected same signal to different slots,but both slots gets called on single click ,but i want that the on first click first slot should get called and on second click second slot..

The reason why I recommend you get yourself some basic knowledge, is that this question has nothing to do with Qt itself. You will run into the exact same issue in any framework and in any language. That's why I think you lack some basic knowledge to be an effective programmer.

ok andre,thanks for your advice,hey i i have tried something,just check out my code,
@#include "dialog.h"
#include "ui_dialog.h"
#include<QCalendarWidget>
#include<QDate>
#include "dialog1.h"
#include "ui_dialog1.h"
#include<QPainter>
#include <QtGui/QApplication>

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

connect(ui->calendarWidget,SIGNAL(clicked(QDate)),this,SLOT(showdate(QDate)));

}

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

void Dialog::showdate(QDate date)
{
ui->lineEdit->setText(date.toString());

void Dialog::showset(QDate date)
{

if(ui->lineEdit->text()==date.toString())
{
Dialog1 a(this);
connect(&a,SIGNAL(setclicked()),this,SLOT(setcolors()));
connect(&a,SIGNAL(unsetclicked()),this,SLOT(unsetcolors()));
a.show();
a.exec();

}
else
{
ui->lineEdit->setText("hello");
}

}@

I will be thankful if anyone check out this code and tell me ..

andre

imrrk, if you show us a piece of code, without telling us what to look for, do you really expect a reply? My guess is: it doesn't work as you expect, right?

Just a hint: you implemented a showset(QDate date) method, but you are not calling it anywhere. I think you should merge the showdate and showset methods into a single method.

vinb

why using:
a.show and a.exec?

imrrk

hello andre,u already know what i want,so i showed my code,to show you what i have tried,and you r right ,i forgot to include that line,where i called showset method..

imrrk

vinb,I have used that to show and execute the dialog

Yes, it is clear what you want, but not what might be wrong with the code you show us. That is what I was asking about. I guess it doesn't do what you want, but that's not what you tell us.

On the show() and exec() calls. Just remove the show() call please, it is nonsense.

imrrk

ok andre,I removed it,what next?

andre

Do you have introduced a call to showset(QDate date) yet? Or better yet, did you follow my advice on merging that method with showdate(QDate date)?

imrrk

i have introduced the call in constructor but also it wont work and do you mean merging in this way

@void Dialog::showdate(QDate date)
{
ui->lineEdit->setText(date.toString());
connect(ui->calendarWidget,SIGNAL(activated(QDate)),this,SLOT(showset(QDate)));

}
void Dialog::showset(QDate date)
{
Dialog1 a(this);

connect(&a,SIGNAL(setclicked()),this,SLOT(setcolors()));
connect(&a,SIGNAL(unsetclicked()),this,SLOT(unsetcolors()));
a.showNormal();
a.exec();
}@
