When a PictureBox is loaded, it displays a picture from the ImageList. What exactly is the ImageList, and how is its content determined?
What is a container object in GUI programming?
A container is another name for an array or vector.
A container is any class that is made up of other classes.
A container is a primitive variable that contains the actual data.
A container is an object like a Frame that has other GUI components placed inside of it.
Add the purple code to your Main Code Section (type it by hand if you get weird errors). It will call the object’s monitorLevels() method, which we will create in this sprint:
userInput = 99while userInput != 0:checkerObj.displayList()userInput = checkerObj.displayMenu()if(userInput == 1):checkerObj.addLevel()checkerObj.writeLevelsToFile() # Write levelsList to LevelsFileelif(userInput == 2):checkerObj.removeLevel()checkerObj.writeLevelsToFile() # Write levelsList to LevelsFileelif(userInput == 3):checkerObj.removeAllLevels()checkerObj.writeLevelsToFile() # Write levelsList to LevelsFileelif(userInput == 4):checkerObj.updateMenuPrice() elif(userInput == 5):userInput = 0 # prevent the app from continuing if the user pressed Ctrl+C to stop itcheckerObj.monitorLevels()
