我想使用Qxt的span滑块而不必安装它.这可能吗? [英] I would like to use the span slider from Qxt without having to install it. Is this possible?
问题描述
我偶然发现了小工具为您提供了带有两个手柄的滑块,因此您可以在上限和下限之间选择一个范围.
I stumbled across a widget that provides you with a slider with two handles so you can select a range between an upper and lower limit.
我想不用安装所有Qxt就可以使用它,因为我很确定这是我唯一需要的东西.
I would like to use it without having to install all of Qxt though, since I am pretty sure this is the only thing that I need.
我如何处理qxt_p()以便将此小部件独立使用?
How can I deal with qxt_p() in order to use this widget as a standalone?
推荐答案
您需要在主类中添加以下内容:
You need to add the following in the main class:
private:
QxtSpanSliderPrivate* d_ptr;
friend class QxtSpanSliderPrivate;
在私有类中的以下内容中:
And in the following in the private class:
private:
QxtSpanSlider* q_ptr;
friend class QxtSpanSlider;
此外,您应该删除Qwt宏用法,并直接访问 q_ptr
和 d_ptr替换
qxt_d()
和 qxt_q()
.
Also you should remove Qwt macros usage and replace qxt_d()
and qxt_q()
with direct access to q_ptr
and d_ptr
.
主类的每个构造函数都应初始化两个指针:
Each constructor of the main class should initialize both pointers:
QxtSpanSlider::QxtSpanSlider(Qt::Orientation orientation, QWidget* parent) :
QSlider(orientation, parent),
d_ptr(new QxtSpanSliderPrivate())
{
d_ptr->q_ptr = this;
//...
}
万一我忘了一些东西,要点在这里.这段代码使我能够在Qt5中成功使用 QxtSpanSlider
.
In case I forgot something, here is the gist. This code allowed me to successfully use QxtSpanSlider
in Qt5.
