Defining or changing a button
When you define a button, you can add a text label, an icon, or text and an icon, then assign a single command or a script to perform.
Another type of button that you can create is a popover button, which displays a popover. See Working with popovers on layouts.
To define or change a button:
1. If you're defining a button that performs a script (as opposed to a single FileMaker Pro command), create the script.
See Creating and editing scripts.
2. In Layout mode, from the Layout pop-up menu, choose the layout for the button. Then:
To define a new button, continue to step 3.
To change a button definition, double-click the button, then skip to step 4.
3. Create a new button or select the object that will serve as the button on the layout.
Do this
Create a new button
In the status toolbar, do the following.
Windows: Click the arrow next to the Button tool Button tool or the Popover Button tool Popover button tool, and choose Button from the menu, then drag the crosshair to draw the button.
macOS: Click and hold the Button tool Button tool or the Popover Button tool Popover button tool, and choose Button from the menu, then drag the crosshair to draw the button.
Tip  You can also choose Insert menu > Button or Popover Button.
Attach a button definition to an existing object or objects, like text or a field
Select the object(s) and choose Format menu > Button Setup.
If you select multiple objects, select only objects that have no previous button definitions. FileMaker Pro groups the objects when you define them as a button. See Using tools to precisely position objects.
If you attached a button definition to an existing object, you can only use an action for the button, so skip to step 5.
4. In the Button Setup dialog box, select a label type for the button.
By default, FileMaker Pro creates a label of text only, center aligned.
To create a label with
Do this
Text only
Click Label text button, then type the label in the text box.
An icon only
Click Image only button, then click an icon from the choices that appear. Scroll or press Up Arrow or Down Arrow to see more choices.
To change the size of the icon, drag the slider (the icon's size changes on the layout), or enter a size (in points).
To use a custom icon, click +. Choose a filename (in PNG or SVG format), then click Open (Windows) or Insert (macOS). For more information about SVG support, see FileMaker Pro SVG Grammar for Button Icons.
To remove a custom icon from the list of choices in this file, select the icon, then click . The icon is removed from the list, but buttons or popover buttons that use the removed icon don't change.
Text and an icon
Click Icon at top, text at bottom button, Text at top, icon at bottom button, Icon at left, text at right button, or Text at left, icon at right button. Type the label in the text box, and click an icon from the choices that appear. Use the information above to complete the label.
5. For Action, choose what you want the button to do.
To perform
No action
Do Nothing (the default). You can also choose this option to disable a button.
One command (such as go to a specific layout)
Single Step. In the Button Action dialog box, select and define a script step, then click OK.
To save the action as a script, click Convert to Script. Enter a name for the script, then click Save (Windows) or OK (macOS). FileMaker Pro saves the script in the Script Workspace. See Creating and editing scripts.
Note  Select Run script with full access privileges to allow the script to do things that normally may not be allowed by the user’s assigned privileges.
A defined script
Perform Script. Choose a script in the Specify Script dialog box, then click OK. (You can choose only one script for each button.) See Specify Script dialog box. To define a script, see Creating and editing scripts.
To specify a different script, click Specify script button.
6. To have the cursor change appearance over the button in Browse and Find modes, under Options, select Change cursor to hand over button.
Buttons are identified by a badge Button badge in Layout mode. If you don’t see a badge, choose View menu > Show > Buttons. If the button has other FileMaker Pro badges associated with it, the button badge could be obscured by the other badges. See Identifying badges on layout objects.
Perform Script is useful if you want to run sub-scripts. You can choose to pause, resume, exit, or halt any script that is currently running when a user clicks the button.
Pause (the default): A paused script remains paused.
Resume: A paused script will be resumed after the button’s script runs.
Exit: A current paused script is exited. If the current script was called by another script, control returns to the original script.
Halt: Execution of all scripts (except the button’s script) is halted.
Button icons in SVG format (the icons provided with FileMaker Pro or custom icons you provide) remain sharp even when the size of the icon is increased. However, if you specify a custom icon in PNG format, the icon should be 256 by 256 pixels for best results on high-resolution displays (such as a Retina display on an iPhone).
