How to connect the object created by Qt-Creator to the class
-
Hi,
I`m a newbie on QT. Could anyone tell me how to connect the objected created in Creator to the new class type, e.g., I created a LCDnumber in QTCreator with the name of 'lcd1', I also created a new LCD in the mainwindows.cpp, how to connect this new LCD to 'lcd1'? Because the properties of 'lcd1' can be easily defined in QtCreator,
Thanks in advance!

Hi,
Your description is not really clear. What do you mean by connect ? Connect like in "signals and slots" ? What do you want to connect to lcd1 ?

Hi, thanks for yor reply. The connection means make them exactly the same. Design the LCD in the QT creator,(for the position design) and define it in the mainwindows.cpp by lcd=new LCDnumber....;
Actually, the original class is the QWT-dial which I load from the QWT example. I used LCDnumber as an example above. I defined a new dial with the dial class, but I also created a dial in the QTcreator by the plugin of QWT. Now, I want to make these two dials as the same one.

Can you show your current code ?

Hi,
I include the class "speedo_meter" from the QWT example, and create the object in the mainwindow.cpp:
@
d_speedo = new SpeedoMeter( this);
d_speedo->setScaleStepSize( 20.0 );
d_speedo->setScale( 0.0, 240.0 );
d_speedo->scaleDraw()->setPenWidth( 2 );
@
I also add a dialMater in the QtCreator with the name of DIAL, how can I make these two objects into the same one?
[edit: added missing coding tags @ SGaist] -
Do you mean create a custom widget containing both the SpeedoMeter and the dial ?
