| 31 | // if you ask the same question in a loop, it is recommended to use AW_repeated_question |
|---|
| 32 | // to avoid asking the same question again and again. |
|---|
| 33 | // |
|---|
| 34 | // Usage : 1. Create a new instance of AW_repeated_question outside the loop |
|---|
| 35 | // 2. call get_answer() inside the loop |
|---|
| 36 | |
|---|
| 37 | // The second way to get rid of unwanted questions is by using a 'unique_id' |
|---|
| 38 | // - if unique_id is set, a toggle "Never ask me again" will be added to the question-popup. |
|---|
| 39 | // - if unique_id is NULp, no such toggle will appear (i.e. the popup can NOT be suppressed!) |
|---|
| 40 | // The latter is recommended |
|---|
| 41 | // - whenever the buttons get generated dynamically |
|---|
| 42 | // - when not asking is REALLY dangerous |
|---|
| 43 | // |
|---|
| 44 | // Whenever you change the meaning of a question, it is mandatory that you change the unique_id!!! |
