I am trying to achieve the same ionic3 behavior in my ionic5 project.
My item background color shall be determined at runtime based on a variable
Ionic3 HTML:
<ion-item [ngStyle]="{'background-color': color, 'color':'#363232'}">
Where color=rgb(255,51,0) or similar. Works in ionic3. Now, what is the ionic5 syntax to enable this?
Thanks, El
Use --ion-background-color instead of background-color.
In html
<ion-item style="--ion-background-color: {{_bckgndclr}}; color: #363232;">
In ts
_bckgndclr: any = 'rgb(255,51,0)';
You can change the color, by changing the _bckgndclr variable in ts.
Thank you.

I would like so if it's possible in the Tinymce editor to disable the color with the copy past from Word for example.
Thanks for the help.
If you console.log value in onEditorChange event of editor after pasting the text, you can see style="color: red;" is added in the pasted text.
In onEditorChange you can use regex to remove color property from style, and then set the edited value.
onEditorChange={(value) => {value.replace(/color(.*?);/i, "")}}
Check this example
Note: The code is according to tinymce react component. You may need to change some code if you are not using tinymce for react
I've created a stencil.js application (app starter) where I would like to use ionic components.
I included Ionic using the cdn following this tutorial (https://ionicframework.com/docs/installation/cdn). I have a problem with the style of some of the components like buttons, toggle etc. The problem is that the primary/secondary/x style is not applied also if I use
color="primary"
I've searched a lot to solve this problem and I saw that the property .ion-color-primary isn't apply to the button like it should, so none of the colors are applied to the button that remains white.
If I use Ionic from cdn in a html page (with no stencil.js) the problem don't happen so I think that the problem it's stencil.
I've the latest stencil version, 4.11.7.
Is there any way to programmatically attach scroll="false" attribute for ion-content, with the help of a directive or other?
We need to hide the default behavior of ionic scroll while the application loading in web.
Thanks..
You have to use
$ionicScrollDelegate
.
$ionicScrollDelegate.$getByHandle('Add Your div Handle').
getScrollView().options.scrollingY = false;

i have button and want to set an icon to it along with the text inside it. their is no property to add icon to button like in smartGwt .. any idea how to achieve it please help.
There are many ways of achieving this.
Way 1 : Easy way
Just set the background image via code.
myButton.getElement().getStyle().setBackgroundImage("path");
Way 2: Another easy way
Set your own html
myButton.setHtml("Pass the html string");
Way 3: Easy but gives more control
myButton.addStylename("buttonStyle")
Use css to style this
.buttonStyle{
color : red;
}
Way 4: Best way according to me
Create your own split button wrapping it around a flowpanel or horizontalPanel, with image as your first widget and button as your another widget. This gives you additional control on image and as well as button. You can have your click handler on image as well as button and you can style each one of them individually.
This is how I achieved setting an icon in my get:button.
Add an extra style class hook, mine below is btn-fa-group to your gwt button. If you use the attribute 'addStyleNames' you can define them in your stylesheet and have multiple classes.
<g:Button text=" Post Your Answer" enabled="false" ui:field="showPostButton" addStyleNames="btn btn-default btn-fa-group" />
Now in your CSS define the following declaration:
btn-fa-group:before {
color: #333333;
content: "\f0c0";
display: inline-block;
font-family: "fontawesome";
}
Some important things to note; don't forget the before selector, make sure the unicode starts with a slash and have fontAwesome installed. Alternatively you can use another glyph icon if you have the font installed.
You can set innerhtml with image in button i.e.
Button button=new Button("<image src='abc.jpg' width='200px' height='300px' />Ok");
Button bt = new Button();
bt.getElement().getStyle().setBackgroundImage("url('path/to/ur/image/imagename.extention')");
also set size of background image wrt to the size of button
bt.getElement().getStyle().setProperty("backgroundSize","30px");
Add a Css Class to your Button is probalby the best solution.
button.addStyleName("ButtonIcon");
How to define the CSS and HTML you can read here.
Yes ,you can .Gwt have a SmartGwt type button called push buttopn
com.google.gwt.user.client.ui.PushButton
You can pass Image object to it as below
Image image = new Image(GWT.getModuleBaseURL() + "/images/search-arrow.png");
RootPanel.get().add(new PushButton(image));
How to change background color of GtkTextView? I tried with normal widget set bg functionality but gtk is just changing border color of GtkText View.

gtk_widget_override_background_color()
This the GTK 3.x+ way (until GTK 3.16). From
https://developer.gnome.org/gtk3/unstable/GtkWidget.html#gtk-widget-modify-base
"gtk_widget_modify_base has been deprecated since version 3.0 and should not be used in newly-written code. Use gtk_widget_override_background_color() instead"
UPDATE: thegtknerd notes that this method too is now deprecated and it has been since 3.16.
gtk_widget_modify_base()
http://library.gnome.org/devel/gtk/unstable/GtkWidget.html#gtk-widget-modify-base
As of gtk3, I believe the proper way to do that is through CSS. Register a gtk style sheet though GtkCssProvider, then you can write this CSS:
textview text {
background-color: #theme_bg_color;
}
We can see the relevant CSS nodes in the documentation for GtkTextView. In this case I put #theme_bg_color which is an adwaita CSS variable, but you can as well put anything that goes in a usual CSS file, like red or #ff0000.
