用不同的线程处理gui

本文介绍了用不同的线程处理gui的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

例如，如果我有一个gui有两个QPushButton和一个QTextEdit，我有一个新的qt和c + +，是否可以在不冻结gui的情况下从一个线程（与gui主线程不同）设置QTextEdit的值？

/这些是我想从线程设置的值（i = 0; i <100; i ++）{ qtextedit.setText（i）; }

解决方案

一个具有排队连接的信号/槽，或者向GUI线程发送事件。

你的例子足够快，不会阻塞GUI。

I'm new in qt and c++, and I have a problem with threads.

For example, if I have a gui with two QPushButton and one QTextEdit, is it possible to set values to the QTextEdit from a thread (different from the gui main thread) without freezing the gui?

// These are the values that I want to set from the thread for(i=0;i<100;i++){ qtextedit.setText(i); }

解决方案

It is possible: either use a signal/slot with a queued connection, or post events to the GUI thread.

Your example is fast enough to not block the GUI though.
