multi plots

[21did21]

Hello world,

i use QtCreator and Qwt, i try to plot in real time 6 curve but i not a master in programmation and it's very difficult for me...

can you help me to:
1°) place my curve correctly
2°) with the good size

i do a project to place 6curve and 4button on a windows, the result is nice (http://imageshack.us/photo/my-images/851/myplots.jpg/) but i want to increase the size of my plot and have a good arrangement
==> the plots have to take the total windows (except button emplacement)

How i have to modify this programm to have bigger plots with a good arrangement ?
main.cpp


#include <QApplication>
#include "MyMainWindow.h"
#include <QGridLayout>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
MyMainWindow fenetre;
fenetre.setWindowFlags(Qt::Window);

QGridLayout *MyGridLayout = new QGridLayout;
MyGridLayout->addWidget(fenetre.get_WindowNumber1(),0,0,3,3);
MyGridLayout->addWidget(fenetre.get_WindowNumber2(),0,3,3,3);
MyGridLayout->addWidget(fenetre.get_WindowNumber3(),0,6,3,3);
MyGridLayout->addWidget(fenetre.get_WindowNumber4(),3,0,3,3);
MyGridLayout->addWidget(fenetre.get_WindowNumber5(),3,3,3,3);
MyGridLayout->addWidget(fenetre.get_WindowNumber6(),3,6,3,3);
MyGridLayout->addWidget(fenetre.get_BUTTONRun(),0,8);
MyGridLayout->addWidget(fenetre.get_BUTTONQuit(),0,9);
MyGridLayout->addWidget(fenetre.get_BUTTONAbout(),1,8);
MyGridLayout->addWidget(fenetre.get_BUTTONContact(),1,9);
fenetre.setLayout(MyGridLayout);
fenetre.show();
return app.exec();
}

Try reworking on the column, row, row span, and column span when laying out the widgert, try using the numbers in this code


// Row 0, Column 0, 1, 2. All these are 3-Rows in height, and 1-Column is Width
MyGridLayout->addWidget(fenetre.get_WindowNumber1(),0,0,3,1);
MyGridLayout->addWidget(fenetre.get_WindowNumber2(),0,1,3,1);
MyGridLayout->addWidget(fenetre.get_WindowNumber3(),0,2,3,1);

// Row 3, Column 0, 1, 2. All these are 3-Rows in height, and 1-Column is Width
MyGridLayout->addWidget(fenetre.get_WindowNumber4(),3,0,3,1);
MyGridLayout->addWidget(fenetre.get_WindowNumber5(),3,1,3,1);
MyGridLayout->addWidget(fenetre.get_WindowNumber6(),3,2,3,1);

//Buttons
// Row 0, 1, 2, 3, Column 3. All these are 1-Row in height, and 1-Column is Width
MyGridLayout->addWidget(fenetre.get_BUTTONRun() ,0,3,1,1);
MyGridLayout->addWidget(fenetre.get_BUTTONQuit() ,1,3,1,1);
MyGridLayout->addWidget(fenetre.get_BUTTONAbout() ,2,3,1,1);
MyGridLayout->addWidget(fenetre.get_BUTTONContact(),3,3,1,1);

i don't understand how i can make a correct ploting...

I think you need to properly configure the min, max, and hint sizes for the widgets defined in QWT.

I think you need to properly configure the min, max, and hint sizes for the widgets defined in QWT.
No much simpler - all plot widgets are uncontrolled by a layout ( only the parent widgets of the plots are ).

QLayout problems are completely unrelated to Qwt ( it doesn't matter if you want to arrange QwtPlots or any other Qt widgets ) and insisting on posting in the wrong group will only result in getting no answer.

Again: the newbie section is made for question like this one !

And about this one (http://www.qtcentre.org/threads/41580-x-bottom-scale-div-linked-to-pixels-even-if-resizing) ?

[Santosh Reddy]

I agree with Uwe
