When I clicks on pieChart chartValueSelected() method called. But now my need is when I click in center in pieChartView, there will be no action perform.
I don't know what kind of chart (or Library) you used.
In this situation, the contents of function you written seem not to matter.
So I will explain the general situation.
You can place a transparent button in the middle of the pie-chart.
Then link that button to your "chartValueSelected()" function.

I'm trying to create a button that works exactly like when I click on rectangle Tool on Tools bar. Meaning I don't want it to create a rectangle by just pressing the button, I'm not gonna use Objectcreate() function. Instead, I want it to wait for the user to push the mouse button on chart and drag it to create a rectangle. Just like when you choose the rectangle tool and the cursor-shape changes.
I've looked the WndObj.mqh, Wnd.mqh and Rect.mqh and couldn't figure it out how does this work.
I appreciate if anyone can tell me how to do it

I have a form with green edit, when the user clicks the search button, the components in red are displayed on the screen. But I want that when the user clicks out of the component area, they disappear. I have no idea how to do this. I saw some people using a layout to cover the whole screen, but wanted to know if there was another way.
Or use the
OnFormclick event with object.visible:=false;
I use a home button on most of my slides with a link back to the agenda for quick jumps during my presentation. That way I avoid flipping through the individual slides and get straight back to the overview.
However, I don't want the home button in my lower right corner to show on each page as it spoils the clean look. I tried to use the mouseover event in combination with a macro but can't get it to run. I thought about making the home button completely transparent and on mouseover I would set the transparency to zero so the button shows up. When I click on it, it would follow the link.
Any help to get me there is highly appreciated.
You do know that you can simply press 1 then Enter to return to the first slide in the show, right?
But to follow up on your "I thought about .." idea, why not add a shape on the slide master in a place that won't get covered up by content in any of the slides, then assign it a Go To Slide 1 action setting. After testing to make sure it does what you want, give it any color you like then make it 99% transparent.
As long as you don't forget where to click, you're good to go.
I am using the "Custom Events" highchart plugin by Black Label, to detect right click in my chart. My goal is to use the right click in the chart as "Back" button when drilling out from my custom data. I know highchart has drilling options embedded, but this is a highly custom application, and my problem is that I need a way to detect right click on the x-axis crosshair line.Since the crosshair is following the mouse, 90% percent of the right clicks is triggered on the crosshair line itself, and I can not manage to detect that click. I need the event to be catched inside highcharts, because there is multiple charts on my page, and I need to know which chart was clicked on, and on what point.
I hope you understand my explanation and problem.

What do you check to see if the up or down arrow in the listbox vertical scroll bar were clicked.
Looked at dozens of post all over the web and no answer.
What I want to do is if they click up or down then make the next visible item in the list the selected one. Make it highlighted.
thanks all
It looks like the control won't do it natively. You will need to implement it yourself. You can use this post as a guideline:

Note that you will need to handle the WM_VSCROLL message rather than the WM_HSCROLL message as depicted in the code sample.
