dialog

问题 I researched on SO about communicating between fragment and fragment dialog, and I found that setTargetFragment and an interface is an approach. But I get this error when I try to setTargetFragment. The method setTargetFragment(Fragment, int) in the type Fragment is not applicable for the arguments (SettingsDetailsFragment, int). I haven;t use fragments until now and I'm new on android. So i have this fragment: public class SettingsDetailsFragment extends Fragment implements

问题 I am using Dialog components from material-ui ReactJs. <Dialog fullScreen open={this.state.open} PaperProps={{ classes: {root: classes.dialogPaper} }} onClose={this.handleClose.bind(this)} transition={this.props.transition}> {this.props.children} </Dialog> In the above code I already override the root classes of PaperProps.

问题 The confirmation dialogues in chrome are not accessible to JAWS screenreader (Version 18.0.2945). I experienced that with a simple onbeforeUnload dialog as well as with a javascript confirm dialog. The text in the dialog will not be read. Did anyone experience similar problems or knows an answer? 回答1: As of today, 18/09/2017, this is a jaws issue. The code works on all other major browsers. There is no solution at present. Just for your information, alert and prompt have the same problem.

问题 I have a program that runs in the Win32 environment. There is one variable that I would like to set before the program begins. The only reason it is a Win32 program is because I am accessing serial ports. I don't care how I input the variable - it is a number and I suppose a dialog edit box would be best - but I don't know how to go about this with Win32! Ignoring the bulk of the program, my code is as follows: #include <windows.h> //Initialise Windows module int WINAPI WinMain (HINSTANCE

问题 I have created a confirm dialog where the user can select yes/no private async Task Confirm(IDialogContext context, IAwaitable<bool> result) { var res= await result; await context.PostAsync(res? "Proceed" : "Ok then"); if (res) { ...... } } If the user selects Yes he will receive the message "Proceed" At the same time (again if "res" is true), i want to send a specific message to the bot without appearing in the conversation. Is there a way to send a custom message back to the bot when user

问题 From what I see, in the nodejs framework, I notice you can't prompt a user within a dialogflow dialog and retrieve the that prompt within the same dialog function... I may be wrong about that. Either way, you can return prompt and retrieve it in the next dialog flow. Is there a way to cut off the awaiting prompt for user input and end or resume an activity of the dialog? I would like to cut the prompt off at a certain point, ideally on a time basis. 回答1: This is possible thru using a

问题 I have a form in a Gtk.Dialog which has an "Ok" button and a "Cancel" button. When I click on the Ok button, the dialog returns 1 and when I click on Cancel button, it returns 0. What I want to make is to validate the fields of the form so that if any field has invalid data, like letters in a numeric field or empty fields, the dialog can not be destroyed if Ok button is pressed. 回答1: You could define a custom dialog. Here you can find an example. Make shure to destroy the dialog only if your
