I'm using Enzyme/Jest for testing my React components. How do I simulate holding down the shift key whilst clicking a button?
It's the same way like you simulate normal clicking the button but with one additional parameter.
enzymeWrapper.find('div').simulate('click', { shiftKey: true });
It should also work with altKey and ctrlKey, but I haven't checked it.

I have a button in C++ Builder 6 that I need to activate (and stay activated). But when I don't need it anymore, I want to click again on that button, and it goes back to the UP state.
Thank you for your help.
if you're working with VCL controls I think you can use a TSpeedButton and implement the toggle logic with its TSpeedButton.Down property. It stays pressed while Down is true and unpressed when Down is false. Check this
there are these properties for this:
TSpeedButton::Down indicates clicked button (you can also programaticaly set it to true/false on runtime)
TSpeedButton::AllowUp enable unclicking on second click
TSpeedButton::GroupIndex if non zero all buttons with the same index are goruped together and only one can be down at time so when you click on one all others are unclicked.
So for single button set AllowUp=true And GroupIndex to unique non zero number and for multiple buttons just set GroupIndex to the same unique non zero number for all buttons.
Cheers!
I'm using ag-grid and I'd like to save the layout/state of the user. Pretty much something like this
This solution forces the user to click on the button to save the preferences ("Save state"). There is some other way/event to detect that the user changed the state of the table (in order, to me to save and avoid to force the user to click on a button for that)?
I was hopping to find some method here but i didn't..
I initially had code that listened to all of the applicable events from the grid, but ultimately, I found it easier to just save the entire grid state in the component's onDestroy method, regardless of whether anything has actually changed.
Found my answer here.
All the events are here but i prefer to add a global event:
addGlobalListener(listener) Add an event listener for all event types coming from the grid.)

I have a classic report with cards. I want to display a value when the user mouseover any of the cards. How can I do that?
One method might be to add a value to card modifiers column, then run a Dynamic Action after refresh of your region, that would execute the following JS (fire on initialisation).
The first jQuery selector is driven by your card modifier value - I used 'titleA'
$('.titleA a').attr('title','Help me');
This should modifer your generated HTML accordingly
There are three mouse related dynamic actions you can use without having to write any JavaScript:
Mouse Enter (mouseenter) - Fires once when the pointing device is moved into the triggering element.
Mouse Leave (mouseleave) - Fires once when the pointing device is moved away from the triggering element.
Mouse Move (mousemove) - Fires when the pointing device is moved while it is over the triggering element.

I would like to know what is recommended way to focus on component from outside the component. I am trying to focus on a input field when the person closes the modal window.
Typically you would use an action in the modal that triggers when the close button is clicked, and you would send the action up to the component with the input with sendAction. In the component with the input, you could then use Ember.$ or any other method to tell the browser to focus on an element.
The situation is more complex if the modal is not inside the component that contains the input. In that case you might need to use a service or event. But it's much easier to use the first method.
I was originally thinking this would be extremely easy to do. Google searches returned results for everything but this.
I am trying to have a normal button that I can click, and it stays down, click again, and it rises back up.
I found one function that did what I wanted, but only worked if the button retained focus, click anywhere else and it rises again.
Button_SetState(GetDlgItem(hwnd, IDC_BTN_SLEEPCLICK), TRUE);
Is there any real way to do this? Or am I gonna need to do this kind of thing by hand?
Thanks.
Create a check box, then set the "push like" property for that check box to true.
You want a checkbox with BS_PUSHLIKE style. To toggle it programmatically, use Button_SetCheck
The "staying down" and "rising back up" are a matter of how you draw the button.
You could create your own button class by using the Paint and Redraw methods.
