I want to add red background and white color for titleStyle for ibutton in smartgwt. I cannot override skin_styles.css. How to override skin_styles for button in smartgwt? Simple addStyleName() or setPrimaryStyleName does not work. Have somebody tried it?setBase Style also.
It seems you have issues with skinning and style, If you want to add a style to a widget(your previous post) you can use some sort of code:
String newStyle;
String actualStyle= o.getStyleName();
if(actualStyle!= null){
newStyle= actualStyle+ " " + styleNameYouWant;
}else{
newStyle= styleNameYouWant;
}
o.setStyleName(newStyle);

I'm a very basic coding person that needs something to work, but IDK how. I have a website where I have 4 images. When you hover over those img they become slightly darker, but I wish there was a way to show some text as well (preview of how it should work: https://imgur.com/a/r5cOW2R)
Here's the link to my GitHub code: https://github.com/Ezzol/HCI-Portfolio
Can anyone explain to me what I need to do to add that hovereffect you can see in my design at the imgur link?
You would want to use the CSS hover event. Here's a good example on how to do that.
https://www.w3schools.com/howto/howto_css_image_overlay.asp
you probably need to use javascript as well, and do an EventListener to tell when it is being hovered over, and then use .style to change it, for example:
var text = document.getElementById("text");
var exampleimg = document.getElementById("exampleimg");
exampleimg.addEventListener("mouseover", examplechange);
exampleimg.addEventListener("mouseout", examplechangeback);
function examplechange(event)
{
text.style.display = "block";
}
function examplechangeback()
{
text.style.display = "none";
}
add a h1/h2/h3/p element to your page, and give it the id "text" then style it how you want and set the display to none.
I'm trying to implement a TinyMCE button that will apply the style of the selection to the entire box. I'm having trouble, though, reading the style of the selection when the selection is buried in a span in a span in a paragraph. Let's consider 'color' for example. Below I have a box with some text and I've selected "here" in the paragraph and made it red.
The HTML for the paragraph is now:
The code behind my button to apply the style of the selection to the box is
var selected_color = $(ed.selection.getNode()).css('color');
console.log("color pulled is ", selected_color);
$(ed.bodyElement).css('color', selected_color);
It doesn't work because the color pulled is black, not red, so the third line just re-applies the black that's already there. (If I replace selected_color in the third line with 'blue' everything goes blue.) So the problem is pulling the color of the current selection.
Does anyone know how I can do this reliably, no matter how buried the selection is?
Thanks for any help.
I also noticed somewhat a strange behavior up and there, with selections of nested span's and div's, but honestly i'm not able to recognize if this is a bug of TinyMCE, a browser issue or a combination of both (most probably).
So, waiting for some more information from you (maybe also your plugin code) in the meanwhile i realized two proposal to achieve what you want: the first plugin behaves like the format painter in word, the second is simply applying the current detected foreground color to the whole paragraph.
As you move throug the editor with the keyboard or mouse, you will see the current detected foreground color highlighted and applied as background to the second plugin button.
Key point here are two functions to get the styles back from the cursor position:
function findStyle(el, attr) {
var styles, style, color;
try {
styles = $(el).attr('style');
if(typeof styles !== typeof undefined && styles !== false) {
styles.split(";").forEach(function(e) {
style = e.split(":");
if($.trim(style[0]) === attr) {
color = $(el).css(attr);
}
});
}
} catch (err) {}
return color;
}
function findForeColor(node) {
var $el = $(node), color;
while ($el.prop("tagName").toUpperCase() != "BODY") {
color = findStyle($el, "color");
if (color) break;
$el = $el.parent();
}
return color;
}
The try...catch block is needed to avoid some occasional errors when a selected text is restyled. If you look at the TinyMCE sorce code you will notice a plenty of timing events, this is a unavoidable and common practice when dealing with styles and css, even more with user interaction. There was a great job done by the authors of TinyMCE to make the editor cross-browser.
You can try out the first plugin in the Fiddle below. The second plugin is simpler as the first one. lastForeColor is determined in ed.on('NodeChange'), so the code in button click is very easy.
tinymce.PluginManager.add('example2', function(ed, url) {
// Add a button that opens a window
ed.addButton('example2', {
text: '',
icon: "apply-forecolor",
onclick: function() {
if(lastForeColor) {
var applyColor = lastForeColor;
ed.execCommand('SelectAll');
ed.fire('SelectionChange');
ed.execCommand('forecolor', false, applyColor);
ed.selection.collapse(false);
ed.fire('SelectionChange');
}
return false;
}
});
});
Moreover: i think there is a potential issue with your piece of code here:
$(ed.bodyElement).css('color', selected_color);
i guess the style should be applied in a different way, so in my example i'm using standard TinyMCE commands to apply the foreground color to all, as i wasn't able to exactly convert your screenshot to code. Please share your thoughts in a comment.
Fiddle with both plugins: https://jsfiddle.net/ufp0Lvow/
deblocker,
Amazing work! Thank you!
Your jsfiddle did the trick. I replaced the HTML with what was in my example and changed the selector in tinymce.init from a textarea to a div and it pulls the color out perfectly from my example. The modified jsfiddle is at https://jsfiddle.net/79r3vkyq/3/ . I'll be studying and learning from your code for a long time.
Regarding your question about
$(ed.bodyElement).css('color', selected_color);
the divs I attach tinymce to all have ids and the one the editor is currently attached to is reported in ed.bodyElement. I haven't had any trouble using this but I have no problem using your
ed.execCommand('SelectAll');
ed.fire('SelectionChange');
ed.execCommand('forecolor', false, applyColor);
Thanks again! Great job!
I've created a small text editor window that allows the user to change some basic properties of a text area included within the screen. Two of the options available to change the properties of the textArea are font color and font color fill, which are both handled by separate color pickers.
I ran into an issue when testing these buttons using the setStyle method that only one property could be saved at a time. Example, if text color was set to BLUE, and afterwards fill color was set to YELLOW, text color would not remain blue, but instead revert back to its default defined in the stylesheet (black).
To fix this problem, I have created the following method;
private void updateTheSyle()
{
this.textArea.setStyle("-fx-control-inner-background: " + toRgbString(this.colorPickerFill.getValue()) +
"; -fx-text-fill: " + toRgbString(this.colorPickerFont.getValue()) + ";");
}
The toRgbString() method is also called, this is simply passing the user input from the color picker into a string such that the setStyle method can pass the correct parameters to the stylesheet.
This solution does work, as it enables me to change both the fill and the font color without reverting back to default upon selection. However, my program includes more than just fill and font color, which will contribute to a far longer setStyle statement as these options are added.
TLDR: Is there a way to edit a single style included in a CSS stylesheet without affecting the other styles in a given class?
For your first question (longer setStyle statement), If we take into account that the style is defined by a String, and it takes a whole set of details to provide for a single Style, so why not use a List<String> :
List<String> example = new ArrayList<>();
String style = "";
//For example if you use 2 textField to get the (value) and (type):
example.add("-fx-"+textFieldType+":"+textFieldValue + "; ");
//To gather all the properties in a single string
for(String property: example){
style += example;
}
yourNode.setStyle(style);
I do not know if there is a better approach but it works, good luck !
Edit :
I think this tip answers your second question:
private void Update(String type,String newValue){
for(int i = 0; i < example.size(); i++){
if(example.get(i).contains(type)){
example.set(i, "-fx-"+type+":"+newValue + "; ");
//Here you add a (break;) to not alter the other similar styles !
}
}
//Here you use a loop to update the new elements changed
}
I hope this will help you solve your problem !
When the user marks a text, he can define a backgroundcolor with the colorpicker (textcolor.plugin).
Once saved he can change the background-color but not get rid of it.
background-color:white is no solution as the bodycolor can be RGB or even a picture.
How is the colorpicker to configure to remove the style-tag or at least insert a background-color:none?
Found a solution changing the plugin (textcolor). If there is a better way please be free to post it.
I added additional colors to the colorpicker. The Color #FFFFFe (near White) i marked as NO COLOR and changed the plugin as shown.
function onPanelClick(e) {
var buttonCtrl = this.parent(), value;
if ((value = e.target.getAttribute('data-mce-color'))) {
buttonCtrl.hidePanel();
value = '#' + value;
buttonCtrl.color(value);
if (value == '#FFFFFe') { //Changing the value to -1 causes deletion :-)
value = -1;
}
editor.execCommand(buttonCtrl.settings.selectcmd, false, value);
}
}
Researched a bit more since the given answer did not work in my version 4.5.0 of tinymce.
The textcolor plugin uses 'editor.formatter.remove(...)' to remove text color or background color upon selecting 'x' in the last option of the color palette for 'no color'.
While that function is used elsewhere successfully in tinymce (e.g. when removing italics from text), in the context of the textcolor plugin it does not remove color formatting.
Solution:
Replace the following in the textcolor's plugin.js:
editor.formatter.remove(format, {value: null}, null, true);
with:
editor.dom.removeAllAttribs(editor.selection.getNode());
...or in the minified version plugin.min.js:
a.formatter.remove(b,{value:null},null,!0),
with:
a.dom.removeAllAttribs(a.selection.getNode()),
...and things start working as intended.
The examples I've seen seem to show how to change the color that shows when the user actually hovers over the textinput field.
However when the validation fails, a generic textInput border qill have a red line over it. My CSS file uses a border skin for the textInput, so I can't see this line.
I was hoping there was a way to highlight the text box when it failed validation, or re-enable the red line feature. I don't want to get rid of my CSS cos it'll totally blow my color-scheme, but any tweak allowing the error line to show would be much appreciated.
This is the CSS:
TextInput, TextArea
{
border-skin: Embed(source='/../assets/images/input_bg.png', scaleGridLeft=8, scaleGridRight=20, scaleGridTop=8,scaleGridBottom=9);
padding-top:2;
padding-left:2;
font-size:11;
}
anything that extends UIComponent (both TextInput and TextArea do) has a style called errorColor. It defaults to red. You can change this to whatever you want.
Additionally, if you've got an image that you are using as a border, you should probably remove the pixels from the middle so that it is an actual border instead of an overlay.
The only way I've managed to find, is that Validator will change the component's borderColor style. I don't think it can be achieved using an image- you'll have to embed the image in a basic GraphicRectangularBorder subclass or similar. You can then add this to your skin class:
override public function styleChanged(styleProp:String):void
{
super.styleChanged(styleProp);
if (styleProp == "borderColor")
{
if (getStyle("borderColor") == getStyle("errorColor"))
{
// show error outline
}
else
{
// hide error outline
}
}
}
