By default if I set the tooltip on the control(s) the tooltips will be displayed when the mouse will be hovered.
However, what should I do if I want to disable the tooltips temporarily? All of them for all controls?
Is there some kind of message which will be sent in this case? Or I should simply jave some kind of variable which will be checked for displaying the tooltips?
I have a chart.js line chart displaying properly. When you hover over the y-axis gridlines, the tooltips display as they should.
I'm trying to convert this to function on a touchscreen, so there is no hover. Is there a way to add a simple parameter to make the tooltip show on both hover and onclick?
Note, I know I could add a custom tooltip and add all of that functionality - I'm trying to see if there's just a parameter I can add as I don't need a custom tooltip.
For Chart.js v2, you can specify those events at the root level of chart options.
options: {
events: ['click']
}
Just add "click" to your tooltipEvents list when specifying the options for the chart
...
tooltipEvents: ["mousemove", "touchstart", "touchmove", "click"],
});
In the fiddle below, I've removed all other events from the list except for click to give you an idea of how it will be like on a mobile
Fiddle - http://jsfiddle.net/8uobybv3/
For ChartJS version 2.8.0, you will need to add both the click and mouseout events to make the tooltip behave the desired way.
The click event would make the tooltip to appear when point is clicked and the mouseout event would hide the tooltip when the mouse pointer is moved outside of the chart canvas area which is the desired behavior.
Note: Without adding the mouseout event the tooltip would not hide even when the mouse is moved or clicked outside the chart canvas area.
Code:
options: {
events: ["click", "mouseout"],
....

I've designed a toolbox control. It's inside a CDockablePane object. Since the tools inside it may need to be scrolled, I've created a CScrollView as a child of the pane and have inserted the tools inside it as children. Based on the pane size, scrollbars of the CScrollView object appear properly, but clicking on them doesn't scroll the view. It seems that they're disabled. When I use SS_NOTIFY style when creating the CScrollView, the CScrollView object receives mouse clicks, but when i don't use the style, it doesn't. But it seems that the scroll bars inside the view control don't receive clicks. When mouse hover over them, no visual effect in scroll bars appears. It seems that the scroll bars are disabled, while I've not created nor manipulate them.
What's wrong?
mouse wheel works. click on scrollbars is received by the scroll view, not by the scrollbars. inside handler, i wrote this code:
CScrollBar *pScroll = GetScrollBarCtrl(SB_VERT);
if (pScroll->GetSafeHwnd())
{
...
if is not true. this means that the scroll view has not a scroll bar, but if so, how is it shown?!
any idea?
...
since i didn't get answer, i'm going to clarify my question with a sample code:
https://dl.dropboxusercontent.com/u/4829119/930501%20-%20t3.zip
in this sample, how can i scroll my view as i do with other views like class view and file view?

Did you initialize by calling SetScrollSizes? The scroll bars are enabled only when the sizeTotal is larger than the view window size.
I'd like to change the default style of the list-view control's tooltips to balloon.
I first called ListView_GetToolTips() to get the HWND of the list-view's tooltips control, and then used GetWindowLongPtr()/SetWindowLongPtr() to add the TTS_BALLOON style.
I handle LVN_GETINFOTIP to customize the tooltip for the items (first column) in the list-view: the tooltip texts that appear for the first column items are actually a copy of the text of the third column. The other columns (subitems) are managed automatically by the list-view.
The balloon-style tooltips for the first column items seem OK; their stems are correctly positioned:
But the tooltips for the second column seem drawn wrongly, e.g. the balloon is drawn as if it was referred to a subitem in a row below the actual row pointed by the mouse cursor.
In the following picture, the "star" indicates the position in which the mouse cursor was when the tooltip appeared, but the tooltip's stem points to a row below, marked with an ellipse:
The strange thing is that the tooltips for the third column seem drawn correctly.
Is this a bug in the list-view control? (I'm using Windows 7.)
Or what am I missing here?
The ListView uses a tracking tooltip and positions it to unfold and reveal the hidden text in a column that's too small. It's not expecting its tooltip to be a balloon and so doesn't compensate for that.
You'd need to sub-class the tooltip itself, watch for TTM_TRACKPOSITION messages from the ListView, and adjust the coordinates.
Your second question - the shaded background comes from the system theme. You should be able to get it by calling SetWindowTheme on the tooltip (I'm not sure why the ListView disables themes for the tip).
I have developed on application, which shows a dialog box with two list controls.
In this list control, I am showing images. Now I want is, when we move the mouse on images from the list control of dialog box, It will show tool tip for that.
How can I show tool tips for images in a list control in a dialog box?
The CToolTipCtrl control is the MFC wrapper class around the Win32 "tool tip". You can use this to display a small pop-up window to describe another control or provide additional information in your app.
If you're using a ListBox control, explore one of these sample projects to see how to display tooltips for individual items displayed within that ListBox control:
ListBox With ToolTip Support
List Box With ToolTips
And if you're using a ListView control (CListCtrl in MFC), then you should start by reading the documentation for the GetToolTips function and the corresponding SetToolTips function. You can also check out how this sample ListView control implements tooltips:
