[merry]

Hi all

Can anybody guides me , Is there anyway to make double sided slider in Qt4.2.

That is there are 2 pointers in the sliders so that we can drag it frm both the sides i.e from right as welll as left.



Thanx

[wysota]

Take a look at http://libqxt.sourceforge.net. AFAIR it contains a double head slider.

Hi Wysota


Take a look at http://libqxt.sourceforge.net. AFAIR it contains a double head slider.


The above Link u sent to me of "QExtensionLibrary ", can be used in Qt4.1 .

And also tell me How to use this Extension Library in Qt4.1.

Thanx

[wysota]

But What is AFAIR...
"As far as I remember"


The above Link u sent to me of "QExtensionLibrary ", can be used in Qt4.1 .
So? You wanted to know how to implement a double headed slider. Take the sources and implement it for Qt3.
http://libqxt.sourceforge.net/docs/classQxtSpanSlider.html


And also tell me How to use this Extension Library in Qt4.1.

Link against it.

This is what you want, right?

Hi. Unfortunately the version of QxtSpanSlider (http://jpnurmi.kapsi.fi/docs/classQxtSpanSlider.html) in libqxt svn trunk is pretty immature. Here are links to revised files:

qxtspanslider.h (http://libqxt.svn.sourceforge.net/viewvc/libqxt/sandbox/jpnurmi/include/qxtspanslider.h?view=markup)
qxtspanslider_p.h (http://libqxt.svn.sourceforge.net/viewvc/libqxt/sandbox/jpnurmi/src/widgets/qxtspanslider_p.h?view=markup)
qxtspanslider.cpp (http://libqxt.svn.sourceforge.net/viewvc/libqxt/sandbox/jpnurmi/src/widgets/qxtspanslider.cpp?view=markup)

They will get merged back to the development branch after certain build system issues have been solved.

Hi

I m working on Qt4.1 on Intel MAC machine

Is it possible to install libqxt on MAC Operating System

Actually I tried to install libqxt

and when I make the file I got errors.


make[1]: *** [QxtApplication_x11.o] Error 1
make: *** [sub-src_gui-make_default] Error 2


pls tell me what should i do now.

[wysota]

Did you run configure first?

[merry]

Yes I run configure first.

[jpn]

Is it possible to install libqxt on MAC Operating System
I'm afraid it's not because nobody in the development team has a Mac.


pls tell me what should i do now.
I suggest you take the class, remove unnecessary includes and export macros and include it directly to your project. See the attachment.

Thanx

I ' ll try this...

[merry]

Thanx 4 d soln.

I tried it

It works but shows Vertical Slider and the two heads on it also cross each other, I dont even understand how it works,

But I m trying to understand it...

QxtSpanSlider (http://jpnurmi.kapsi.fi/docs/classQxtSpanSlider.html) inherits QSlider so you can make it horizontal in the same way. Either pass Qt::Horizontal to the constructor or use QAbstractSlider::setOrientation() (http://doc.trolltech.com/4.3/qabstractslider.html#orientation-prop).

Lower boundary value of the span:

QxtSpanSlider::lowerValue() - returns the lower boundary of the span
QxtSpanSlider::setLowerValue(int lower) - sets the lower boundary of the span
QxtSpanSlider::lowerValueChanged(int lower) - a signal which is emitted whenever the lower boundary of the span changes


Upper boundary value of the span:

QxtSpanSlider::upperValue() - returns the upper boundary of the span
QxtSpanSlider::setUpperValue(int lower) - sets the upper boundary of the span
QxtSpanSlider::lowerUpperChanged(int lower) - a signal which is emitted whenever the upper boundary of the span changes


In addition, QxtSpanSlider (http://jpnurmi.kapsi.fi/docs/classQxtSpanSlider.html) provides QxtSpanSlider::setSpan(int lower, int upper) and QxtSpanSlider::spanChanged(int lower, int upper).

How Can I add QSpinBox in the file "QxtSpanSlider" u had given me yesterday ,for showing lower head and upper head values in the spinboxes.
Do you mean how to connect corresponding signals and slots?


connect(lowerSpinBox, SIGNAL(valueChanged(int)), spanSlider, SLOT(setLowerValue(int)));
connect(upperSpinBox, SIGNAL(valueChanged(int)), spanSlider, SLOT(setUpperValue(int)));
connect(spanSlider, SIGNAL(lowerValueChanged(int)), lowerSpinBox, SLOT(setValue(int)));
connect(spanSlider, SIGNAL(upperValueChanged(int)), upperSpinBox, SLOT(setValue(int)));

[merry]

Thanx jpn

But I knw how to connect QSPinBox and Sliders.

Sorry, I don't understand what do you mean. Could you rephrase, please?

[merry]

Actually I want that Where the double headed Slider is shown ,there only On the same widget the Spinboxes Should be shown ,

I mean how can I view QSpinBoxes on the same widget where QextSpanSlider is shown..

How can i do this Wheather i should make a diff class for QSpinboxes or use it in the same class that is for QExtSpanSlider...

Hope so ,now u understand what i wanted to say......

Thanx

[merry]

Thanx to all

My Problem is solved
