[英]Timer, click, mousedown, mouseup events not working together
Looking for some help on a problem Im having 寻找一些问题的帮助我有
sorry if this question has already been asked, I can not find anything similar. 对不起,如果这个问题已被提出,我找不到类似的东西。
The idea is when a picturebox is clicked changed the image to ON. 这个想法是当点击图片框时将图像更改为ON。
If the picture box is held for more than 2 seconds to open a new form and leave the picturebox as OFF. 如果图片框保持2秒以上以打开新表格并将图片框保留为OFF。
However if the picturebox is clicked ON and then held for 2 seconds and then returns i need the picturebox state to remain ON. 但是,如果点击图片框然后保持2秒然后返回我需要图片框状态保持为ON。
Here is what I have tried so far. 这是我到目前为止所尝试的。
I believe for this to work correctly I need to stop MouseUp event from occuring. 我相信为了正常工作我需要阻止MouseUp事件发生。
Is there a way I can stop MouseUp when Tick occurs? 有什么方法可以在Tick发生时停止MouseUp吗?
Is there a easier / better way to do this? 有没有更简单/更好的方法来做到这一点?
Any help would be appreciated. 任何帮助,将不胜感激。
private void time_HoldDownInternal_Tick(object sender, EventArgs e)
{
time_HoldDownInternal.Enabled = false;
time_HoldDownInternal.Interval = 1000;
form1show.Visible = true;
}
private void pb_pictureBoxTest_MouseDown(object sender, MouseEventArgs e)
{
mainMenuVariables.mousedown = true;
time_HoldDownInternal.Enabled = true;
}
private void pb_pictureBoxTest_MouseUp(object sender, MouseEventArgs e)
{
mainMenuVariables.mousedown = false;
//MessageBox.Show("mouse up");
time_HoldDownInternal.Enabled = false;
time_HoldDownInternal.Interval = 1000;
}
private void pb_pictureBoxTest_Click(object sender, EventArgs e)
{
if (mainMenuVariables.mousedown == true)
{
if (mainMenuVariables.pictureBox == false)
{
mainMenuVariables.pictureBox = true;
pb_pictureBoxTest.Image = new Bitmap(mainMenuVariables.pictureBoxOn);
return;
}
if (mainMenuVariables.pictureBox == true)
{
mainMenuVariables.pictureBox = false;
pb_pictureBoxTest.Image = new Bitmap(mainMenuVariables.pictureBoxOff);
return;
}
}
if (mainMenuVariables.mousedown == false)
{
//nothing
}
}
Rather than starting a timer, just record the current time on mouse down. 而不是启动计时器,只需记下鼠标按下时的当前时间。 Then in mouse up, check if it has been 2 seconds. 然后在鼠标中,检查它是否已经是2秒。 eg: 例如:
private void pb_pictureBoxTest_MouseDown(object sender, MouseEventArgs e)
{
mainMenuVariables.mousedown = true;
mainMenuVariables.mousedowntime = DateTime.Now;
}
private void pb_pictureBoxTest_MouseUp(object sender, MouseEventArgs e)
{
mainMenuVariables.mousedown = false;
var clickDuration = DateTime.Now - mainMenuVariables.mousedowntime;
if ( clickDuration > TimeSpan.FromSeconds(2))
{
// Do 'hold' logic (e.g. open dialog, etc)
}
else
{
// Do normal click logic (e.g. toggle 'On'/'Off' image)
}
}
