Haven't coded in years, and started to play around with Google App Maker last week. As the title suggests, I have a couple questions.
I'm trying to figure out if there's a way to dynamically change the color of a button upon click. Right now I have the button changing enabled status to false on click, and using CSS style to change the color of disabled buttons to gray. Is there a way to do this without disabling the button?
Is there a way to wrap text in a button? Right now I am overlaying a Label on the button with the correctly styled font, but would ideally like to have that text be from the Button, as the space the label takes up is not clickable.
Thanks in advance for any help!
add some lines to your page or global styles this
this should let you wrap text.
.app-Button {
white-space: pre-wrap;
}
Say you want to change your button blue when a Boolean value gets changed to "true" in your data source.
add a class to your styles
.blue{
background: blue;
}
then select your button and in the property editor>Display>styles click the drop down and select binding
set the binding to
=#datasource.item.**YourBooleanItem** === true? ['blue']:[]
Clarification there are two steps
Define a CSS class
Add the Class to the "styles" property of
your widget.
The Answer above uses a "binding" but also means that you've got to have an Item with this binding which you may not want.
I wanted a 'decimal' button to be orange when it was active. So on the Page I created a DecimalActive property. I used the onAttach event to set this property to false.
I created a CSS Class (local to the page) named Orange and Normal
.Orange {background:orange};
.Normal {background:white};
Then the following is my onClick
onClick(widget,event)
{
widget.root.properties.DecimalActive = !widget.root.properties.DecimalActive;
widget.styles = widget.root.properties.DecimalActive ? ['Orange'] : ['White'];
}
The challenge was figuring out exactly what AppMaker wanted in the styles []. I don't think it puts applied styles in this array. At least they didn't show up when I console.log(JSON.stringify(widget.styles);
I have verified that this does work (Dec 2019)
I think this answer is clearer and if someone wants to bind it the color change they still can.

I have a form which contains multiple input widgets like textbox, dropdown, textarea, suggestbox, radiogroup and multiselect etc
The input widgets are by default in disabled state.
When I click on a button all of them get enabled.
I would also like their text-color to change when I click on that button.
Note: I dont want to change the widget's label color. Only the value color.
How to do it in code for each? If you could give one example for each widget i.e textbox, dropdown, multiselect,radigroup etc
Looking for a generic solution.
Say you want to change your text box text red when you click the button. add a class to your styles tab like
.red{
color: red;
}
then say you have text box called textbox1 in the onclick event of your button put the following code:
widget.root.descendants.textbox1.styles = ['red'];
same for all the other types
To give you an idea I was testing with TextBox and worked but with TextAreas the Input or Value did not change, as well as the other multiselect and radioGroup options it did not take the css as expected.
When you click on the text box and from the CSS Page Style you start typing "." you will find different options for the widget selected. Using TextBox there is an Input option so you create a Global Style like this one.
.color Input{
color:teal;
}
This will change the Input of the TextBox, the same as if you do with Label, just use the same css class just change the option you want to modify. .color Label {}.
Also to apply the change to the widget just create a function like this one.
function textBoxColorChange() {
app.pages.NewPage.descendants.TextArea1.styles = ["color"];
}
And create an OnClick event to a button to make the change.
With the other widgets I don't have the time to keep testing but I hope this helps to get the idea. Greetings.
I may not have described the issue accurately with the title, but it's easier to explain here:
I have a button that has an icon image contained within it. I need to get rid of the grey box around that icon and keep the icon itself, along with the button functionality. I assigned the button a second class called "nogray", and in my styling sheet I set opacity to 0.
However, this got rid of the entire button, along with the little orange trash bin icon, which I need to be visible. Essentially, I need the button to function the same way, just with the orange icon and no grey box. In this screenie, you can see the buttons at the top of each bulletin note.
Here is the button code in the bulletin notes view:
<button class ="remove-card nogray" id="#item.BulletinId" type="button"><i
class="fa fa-trash"></i></button>
And here is the css for the button:
i.fa.fa-trash::before {
content: "\f1f8";
}
.remove-card.nogray {
opacity:0;
}
(i.fa.fa-trash::before targets the trash icon, and .remove-card.nogray targets the outer gray area. However, I suspect that the latter is targetting the entire button because setting the opacity to 0 affects both gray area and icon.
How would I tweak the button code so that the opacity is 0 only for the grey, and not the icon? I've tried changing the order of the code element by element, but a lot of it is guesswork because this is a team effort and I did not personally write the button code. I'd also like to apologize in advance if this is an impossible question to answer; if there's some detail you need to know, please tell me and I will edit this to include it.
Thank you very much for any suggestions!
I realized I was targeting the wrong lines of code in my css. There was an ActionLink that a teammate commented out, and I assigned the classes from that to my original button code and was able to target the button that way instead.
After trying to find a solution for Centering Text on a Button with Offset, I'm doing now a custom component.
The goal is to make a button-like component that has an icon on one side and a centered text filling the rest of the button.
The component contains either two Label/ Buttons to display the Icon and text. Both of them have a background Image, defined in css.
The css looks like this for Icon and the text with exchanged image as background for text
#button-icon-cancel{
-fx-font-family: "Arial";
-fx-padding: 0,0,0,0;
-fx-background-color: transparent;
-fx-font-size: 28px;
-fx-graphic: url('images/button/cancel.png');
}
#button-icon-cancel:pressed{
-fx-graphic: url('images/button/cancel-pressed.png');
}
The images are loaded by setId(). Currently both components are added to a Panel before passing to the stage. They contain an OnClickEvent for processing.
Now to the actual question
How can I achieve that if one Component is clicked, the other one is getting the :pressed from css as well?
Adding the ClickEvent to the Panel is doing nothing (regarding clicking on either Label/ Button)
Adding both of them to a HBox, adding the Event to the HBox work in that regard, that I can click either component and the Event gets fired, BUT the :pressed State is only applied to the component you clicked.
Is it possible to give all childs the notification, that they should behave like they got pressed? Since we have a lot of small Icon, but only one background for the text, placing a Label over the whole thing create a lot of unneeded wasted Image space. Also this would cause the problematic for changing font color if not all css are changed at once (the label-over-button-solution with .setMouseTransparent(true) wouldn't change the font color of the text label since the label doesn't notice button is pressed)
First of all, JFX-8 will support wider range of css improvements, which will allow you to solve the issue easier.
To solve your issue, i can suggest the following : each node have a pressed property. You can add a listener on this property, and when it changes to true, use setStyle(String) method on needed nodes, and use setStyle(null | "") on changing to false.
I may be trying to get too fancy on this one.
I have a pair of radio-like buttons in a row with a divider between them with background images. When one of the 'buttons' is clicked, I change its class. The CSS for the divider is keyed to the classes of the buttons on either side to select a background image. I am doing this with CSS 'sibling' selectors.
I have jQuery .click events tied to the 'buttons'. the first thing they do is clear the 'selected' class from the other button and set it on the button that was clicked.
For example, if the LEFT button class='selected' and the RIGHT button is not, the divider between them will get a blue background. Click on the RIGHT button and it gets class='selected' while the LEFT button's class is cleared. The divider turns red.
This works in IE, FF, Safari, etc. But IE is odd (IE7) - it will only reflect the divider background change when I mouse OFF the button I clicked! That is, in the example, the RIGHT button gets class='selected' and changes immediately on the click. But the divider stays blue until I mouse off the button, then it turns red.
The class itself IS changing and the button's appearance changes as a result. It's only the neighboring stuff that doesn't!?
It reminds me of my old VB6 days when you had to periodically call 'DoEvents' to get Windows to make UI changes. Could there be something similar here for IE?
I have no idea why this helps, but adding .hide().show() to a selector that includes the stuff that changed class seems to make it update.
I've read that using setAttribute to change the class will force IE7 to re-render the styles. Try that, and if it still fails, I've solved a similar IE7 problem by rewriting the html, which forced IE7 to re-render (using jquery):
if ($("html").hasClass("ie7")){
var tempHolder = $("#ajaxresults").html();
$("#ajaxresults").html(tempHolder);
}
As for giving the html or body tag the ie7 class, I recommend taking a look at html5boilerplate.com. If for some reason you can't use their solution, the jquery for it is:
if ($.browser.msie){
if ($.browser.version < 8){
$("html").addClass("ie ie7");
}
else {
$("html").addClass("ie");
}
}
On some of my pages I am setting focus on a first input element:
$(':input:visible:first').trigger('focus');
If the first input element is a checkbox or a radiobutton it receives a focus fine but that's not clearly visible, so it's label is not highlighted and screen reader doesn't recognize that, too, i.e. it doesn't read out that field. Is there any way using JQuery to make focus on checkbox or radoibuttons more pronounced?
Can't you assign a suitably clear css class to it?
$(':input:visible:first').focus(function() {
$(this).addClass("superClear")
})
.blur(function() {
$(this).removeClass("superClear");
}).focus();
