Application of state machine idea in program design author: Zhang June Published: 2015-09-13 12:20 read: 1314 recommendations: 3 [Favorites]　　The concept of a state machineState machine is an important concept in software programming, and it is more important than this concept to apply it flexibly. In a clear and efficient program, there must be a state machine figure.For example, a key command resolver, it can be considered as a state machine: a state, the trigger a button after the switch to t

QT keyboard events are part of the QT event System, so all rules in the event system are valid for keystroke events. The following concerns are part of the key-specific section:FocusA qwidget that has focus can accept keyboard events. The window with the input focus is the active window or the active Window child window or child window, and so on.The focus moves in several ways: Press Tab or Shift+tab Note: Text compiler (usually r

----------------------------------------Some information has also been found online:About the difference from several other functions:Short getkeystate (int nvirtkey);Short getasynckeystate (int vkey);BOOL getkeyboardstate (pbyte lpkeystate);The maximum difference between the three key status functions is:The first one is to get the keyboard message from the Windows message queue and return to the key status.The second one is to directly detect the hardware interrupt of the keyboard and return t

more general OnP Ressed and onreleased signals, in general. You can use both signals to handle most keystrokes (please compare keypressevent and keyreleaseevent in Qt C + +). They have a name that is the KeyEvent parameter of the event. Includes specific information about the keystrokes.KeyEvent represents a keystroke event. Assuming a key is processed, the event.accepted should be set to true to prevent it from being passed on, and if you do not set

window creation example there is a new function we have not seen before: cvwaitkey (). this function causes opencv to wait for a specified number of milliseconds for a user key stroke. if the key is pressed within the allotted time, the function returns the key pressed; * otherwise, it returns 0. With the construction: while( 1 ) {if( cvWaitKey(100)==27 ) break;} We tell opencv to wait 100 MS for a key stroke. if there is no key stroke, then repeat ad infinitum. if there is a key stroke and
