multi plots

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

Code:

---

#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

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.

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 !

Uwe

And about this one ?

I agree with Uwe
