Today, I would like to share with you the relevant knowledge points about how Qt realizes interface switching by creating window objects. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article. Let's take a look.

Step 1:

Add a pushButton button to the ui file of the main interface

Then create a new window and create a new Qt designer interface class under the project, as shown below:

We choose Widget, which the user can choose as needed, and then enter the class name windowRun.

After the creation is completed, the figure is as follows:

Step 2: associate the pushButton clicked () signal and slot function runSolt () of the ui interface, part of the code:

{

Ui- > setupUi (this)

Connect (ui- > pushButton,SIGNAL (clicked ()), SLOT (runSlot (); / / associated signal slot

}

Step 3: create the windowRun class object win, set the size, and display

Void Example::runSlot (void)

{

QDebug ("Run slots")

/ / Show a new window

Win = new windowRun ()

/ / set the win window size to be the same as this window size

Win- > setGeometry (this- > geometry ())

/ / display

Win- > show ()

}

After running the program, you can jump to the second interface after clicking the button.
