public static bool DisplayDialog (string title, string message, string ok, string cancel= "");

パラメーター

ok OK ボタンに表示するラベル
cancel キャンセルボタンに表示するラベル

戻り値

bool Returns true if the user clicks the OK button. Returns false otherwise.

説明

This method displays a modal dialog.

Use it for displaying message boxes in the Editor.

ok and cancel are labels to be displayed on the dialog buttons. If cancel is empty (the default), then only one button is displayed. DisplayDialog returns true if ok button is pressed.

For dialog boxes that might be shown repeatedly, consider using an overload of this method that takes a DialogOptOutDecisionType as described in the below the code example.

Dialog box that shows info on the number of objects to be placed on the surface.

dialogOptOutDecisionType The type of opt-out decision a user can make.
dialogOptOutDecisionStorageKey The unique key setting to store the decision under.

戻り値

bool true if the user clicks the ok button, or previously opted out. Returns false if the user cancels or closes the dialog without making a decision.

説明

This method displays a modal dialog that lets the user opt-out of being shown the current dialog box again.

Use this method to display dialog boxes in the Editor that might be shown repeatedly. Choose which DialogOptOutDecisionType to use based on how often you think users encounter this message and how often you want to remind them of it.

If the user opts-out of seeing the dialog box associated with the provided dialogOptOutDecisionStorageKey, Unity doesn't show the dialog box and this method immediately returns true.

ok and cancel are labels displayed on the dialog buttons. If cancel is empty, the button displays as "Cancel". This is the default setting. DisplayDialog returns true if the user presses the ok button.

If the user opts-out of the dialog box, Unity stores this decision. If dialogOptOutDecisionType is set to DialogOptOutDecisionType.ForThisMachine Unity stores the decision via EditorPrefs.SetBool. If dialogOptOutDecisionType is set to DialogOptOutDecisionType.ForThisSession Unity stores the decision via SessionState.SetBool. In both cases Unity stores the decision under the key provided as dialogOptOutDecisionStorageKey.

If you want to the let the user change the decision that is stored in EditorPrefs, you can add this to the Editor Preferences with a SettingsProvider.

Use DialogOptOutDecisionType.ForThisSession to show a dialog before a user performs a destructive action that might lose some of their work. If you think the user might see this dialog too often, you can add an option to the Editor Preferences with a SettingsProvider by using EditorPrefs and query that setting before showing the dialog.
