| 00:00 | Welcome to the Spoken tutorial on LibreOffice Base. |
| 00:03 | In this tutorial, we will learn how to Add a Push Button to a form. |
| 00:10 | In the last tutorial, we learnt how to add a list box form control to a form. |
| 00:17 | Now in this tutorial, we will learn how to add push buttons to a form. |
| 00:24 | Let us first invoke the LibreOffice Base program, if it's not already open |
| 00:36 | And open our Library database. You probably know how to open an existing database by now. |
| 00:45 | Click Open under the File menu and choose Library database. |
| 00:52 | Now we are in the Library database. |
| 00:56 | Let us open the 'Books Issued to Members' form that we were working with in the last tutorial. |
| 01:04 | To do this, let us click on the Forms icon on the left panel |
| 01:09 | And then right click on the 'Books Issued to Members' form on the right panel. |
| 01:16 | Now click on Edit. |
| 01:19 | We are now in the form design window. |
| 01:23 | Before we talk about adding Push buttons to our form, let us make some way for the second list box for Member names. |
| 01:34 | Remember, we had an assignment of creating the second list box in the previous tutorial. |
| 01:41 | First, let us remove the text box that is on the right of the Member Name label |
| 01:50 | by right-clicking on this text box and then clicking on Cut. |
| 01:57 | The text box is deleted. |
| 02:00 | Next, let us arrange the form elements. |
| 02:04 | Since list boxes need more space than text boxes, we will push the form elements further down on the form. |
| 02:15 | Here is how we will do it. |
| 02:17 | First let us select all the form elements that are below the Book title label. |
| 02:26 | For this, we will use the click, drag and drop method. |
| 02:32 | Next, let us click on the selected area and drag it vertically down, |
| 02:39 | so that there is enough room for the first list box that is adjacent to the Book Title label. |
| 02:48 | Now, let us repeat the same step for the Member Name label as well. |
| 03:05 | Now, let us click, drag and drop the second list box, that is to the left of the Member Name label |
| 03:14 | And move to its right, so that it is aligned with the rest of the form controls nicely. |
| 03:22 | Okay, let us save our work on the form so far, by using the keyboard shortcut Control S. |
| 03:32 | Now, we are ready to add Push buttons to our form. |
| 03:39 | A push button is another example of a form control. |
| 03:44 | We are familiar with OK, Cancel, Next, and Finish buttons; these are some examples of Push buttons. |
| 03:56 | With Base, we can add these Push buttons to our form and instruct Base, to perform specific actions when clicked. |
| 04:07 | Again, Save or Undo, or Delete are some examples. |
| 04:14 | Let us see how. |
| 04:17 | Let us now add four push buttons to our form, below all the other form elements, just as in the image shown here. |
| 04:30 | To do this, let us go back to our form design window. |
| 04:35 | And, click once on the Push button icon in the Form Controls toolbar. |
| 04:43 | This icon looks like a button with the word Ok on it. |
| 04:50 | Notice that the mouse pointer looks like a plus symbol. |
| 04:57 | Now let us draw our first button on the bottom left, by clicking, dragging and dropping on the form, below all the other elements. |
| 05:10 | And, we will resize it accordingly. |
| 05:14 | Now let us repeat the above step three more times, |
| 05:27 | and now, we have three more buttons, all aligned in one horizontal line. |
| 05:35 | We are done drawing the push buttons on the form; now let us change their labels. |
| 05:43 | To do this, double-click on the first button. |
| 05:49 | We now see the Properties window. Here let us type 'Save Record' against the 'Label'. |
| 05:59 | Now, let us click on the second button on the form. |
| 06:06 | And in the properties window, we will type 'Undo Changes' against the 'Label'. |
| 06:15 | For the third and the fourth buttons, let us type 'Delete Record' |
| 06:25 | and 'New Record' respectively. |
| 06:31 | Now let us define their actions. |
| 06:37 | To do this, let us click on 'Save Record' button, |
| 06:43 | And in the Properties window, let us scroll down until we spot the 'Action' label. |
| 06:51 | Here, we will click on the drop down list box and click on the 'Save record'. |
| 06:59 | Let us follow the same steps for the other three buttons. |
| 07:05 | For the 'Undo Changes' button, we will choose the 'Undo changes' action. |
| 07:12 | For the 'Delete Record' button, we will choose the 'Delete Record' action |
| 07:18 | And for the 'New Record' button, we will choose the 'New Record' action. |
| 07:25 | So, now we have added the push buttons. |
| 07:29 | Okay, let us save our form by using the keyboard shortcut Control S, and close this window. |
| 07:40 | In the next tutorial, we will go through just three more simple modifications to our form |
| 07:47 | and then we can use the form for data entry and data updates. |
| 07:54 | For example, when a Library member returns a book, we can update this information in the database using this form. |
| 08:06 | Here is an assignment: |
| 08:08 | Add a fifth push button to the form beside the fourth, and when used, it should refresh the form. |
| 08:18 | And add 4 narrow push buttons in the next line below. These buttons should help us navigate through the records. |
| 08:30 | This brings us to the end of this tutorial on LibreOffice Base |
| 08:35 | To summarize, we learned how to:Add a Push Button to a form. |
