When I use button to show sheet, after the sheet is pulled down, it is automatically displayed again.
Add argument ondismiss
.navigationBarItems(trailing: Button(action: {self.showEditorInfo.toggle()}) {
Image(systemName: "paperplane")
}.sheet(isPresented: $showEditorInfo, onDismiss: {self.showEditorInfo.toggle()}) {
Text("123")
})
}
When the sheet gets pulled down your view gets redrawn and because showEditorInfo is true the sheet gets presented again. Make sure you reset the value in onDismiss:
.sheet(isPresented: $showEditorInfo,
onDismiss: { self.showEditorInfo = false }) {
Text("123")
}
You may want to pass showEditorInfo as a binding into the next view so that you can dismiss it programatically. That's why it is important to set the value to false in onDismiss and not toggle it.
There are two unrelated issues here: the first is the toggle() in your onDismiss handler, the second appears to be a Simulator bug with an easy workaround.
isPresenting takes a binding as an argument, which tells you the sheet will react to changes in showEditorInfo's value but also that it'll modify that value to reflect the state of the UI. When you drag down on the sheet to dismiss it, showEditorInfo is automatically set to false. In your code, you were toggling it back to true.
After addressing #1, your issue is fixed on devices but still occurs in the Simulator. The cause seems to be that your sheet is attached to the Button in your navigationBarItems. If you put the sheet on the NavigationView itself, or literally anywhere except the Button, it behaves as expected in the Simulator.
struct ContentView: View {
#State var showEditorInfo = false
var body: some View {
NavigationView {
Text("ContentView")
.navigationBarItems(trailing:
Button(action: {
self.showEditorInfo.toggle()
}) {
Image(systemName: "square.and.pencil")
})
}
.sheet(isPresented: $showEditorInfo) {
Text("Sheet")
}
}
}

I was trying to use JQuery UI Sortable plugin for multiple tables. The idea was to grab and drop elements in cells of a table, by connecting all <td> tags with this plugin.
It looks like this: https://jsfiddle.net/Lhm3z0bw/3/
By changing zoom with mouse wheel controls, we can actually grab the elements already placed in the table.
However, when the scale is changing, moving them makes a shift on the current grabbed element.
I tried adding some functions from the JQuery UI API for resetting positions for the element or updating the helper, but there's no good results on it.
$(".sortableCards").sortable({
connectWith: ".sortableCards",
containment: "window",
scroll: false,
placeholder: "sortable-placeholder",
items: ".card1",
forcePlaceholderSize: false,
sort: function(evt,ui) {
//////////
// Maybe some fix needed here ?
//////////
}
receive: function(event, ui) {
if ($(ui.sender).hasClass('cards')) {
if ($(this).find('.card1').length > 2) {
$(ui.sender).sortable('cancel');
} else {
ui.item.clone().appendTo($(ui.sender));
}
}
}
});
Here is another linked question with the same issue : How to get JqueryUI Sortable working with Zoom/Scale - mouse movements
As a means to learn, I am trying to build an autocomplete feature. I am following this example:
https://codesandbox.io/s/8lyp733pj0.
I see two issues with this solution:
1.) Conflict with mouse hover and keydown. If I use the keypad to navigate the list the active item gets highlighted and if I use my mouse at the same time another item will get highlighted. This results in 2 highlighted fields.
2.) If i select an item by pressing enter it will fill the input field with the selected text but if I press enter again it will change that text to the index 0 item I believe.
Can someone please help me in understanding how to resolve these issues. I have tried hover and focus for css but it still doesn't achieve the expected outcome.
My approach (not sure if this is the correct one):
If keyboard is being used then the mouse event should be disabled and vice versa.
I've also tried removing this.setState({activeSuggestion: 0}) for the enter event.
Thanks for your help - it's taking me some time to grasp the concepts of state with React.
The onKeyDown function updates correctly the value ofactiveSuggestion. I sugest you to add a scroll in the select when activeSuggestion is not vissible.
In my opinion, you need to update the value of activeSuggestion with theonMouseEnter function.
When you do that, remember to remove the line 32 from styles.css: .suggestions li:hover.
Only the element with .suggestion-active must have the active styles. Not the hovered ones. The idea is that onMouseEnter must update the value of activeSuggestion.
Here is the code:
// Autocomplete.jsx
//in line 84, after function onKeyDown, add:
onMouseEnter = e => {
try {
e.persist();
const currentIndex = parseInt(e.target.dataset.index, 10);
this.setState({ activeSuggestion: currentIndex });
} catch (reason) {
console.error(reason);
}
}
// then, create const onMouseEnter after the render() method:
render() {
const {
onChange,
onClick,
onKeyDown,
onMouseEnter,
state: {
activeSuggestion,
filteredSuggestions,
showSuggestions,
userInput
}
} = this;
// In the li nodes (line 123), add props onMouseEnter and data-index:
<li
className={className}
key={suggestion}
onClick={onClick}
onMouseEnter={onMouseEnter}
data-index={index}
>
{suggestion}
</li>
Remember to remove the line 32 from styles.css: .suggestions li:hover.
Hope it helps.
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 got one issue that im stacked on.
Im running the media uploader window from a colorbox modal window, which i set to 90% width, and inside i have button which trigger the media uploader (opens second window).
but when i trigger it, it everytime opens smaller modal window than the parent colorbox modal.
i think the problem is that my first window is an Iframe and when i trigger another modal, it takes the iframe as main window and by some percentage it makes the second window smaller. this could fix if i know where to set, that the second window should be 100%.
Do you know where can i set the width and height for the window with media uploader? i tried with the "40" value, but it doesnt work. i cant find no documentation for this.
thanks for reply.
screenshot here: screencast link
my code is
var file_frame1;
jQuery('#mxn_button_add_img1').on('click', function(event) {
event.preventDefault();
// If the media frame already exists, reopen it.
if (file_frame1) {
file_frame1.open();
return;
}
// Create the media frame.
file_frame1 = wp.media.frames.file_frame = wp.media({
title: jQuery(this).data('uploader_title'),
width: 40,
button: {
text: jQuery(this).data('uploader_button_text'),
},
multiple: false // Set to true to allow multiple files to be selected
});
// When an image is selected, run a callback.
// When an image is selected, run a callback.
file_frame1.on('select', function() {
var selection = file_frame1.state().get('selection');
selection.map(function(attachment) {
attachment = attachment.toJSON();
jQuery('#mxn_input_img1').val(attachment.url);
jQuery('#mxn_post_img1').attr('src', attachment.url);
return false;
});
});
});
I have some small canvas, and i have to show border around them, i did that using rollover and rollout evenets, (these canvas hold product images), here rollover and rollout are working perfectly fine, but when a user clicks on some canvas, it has to be selected, means it has show the border around it, and rest canvas should work as normal. but when i select another canvas the previously selected canvas should get unselected and new clicked canvas gets the selection,
but the problem which is coming the rollOut event which is applied on canvas, on a click the canvas get selected, but when rollOut takes place it unselect the canvas, i even removed the rollOut listner on the click of a canvas, but in that case, the clicked canvas will not get unselected , when other canvas will be clicked
can.addEventListener(MouseEvent.ROLL_OVER,onRollOverThumb);
can.addEventListener(MouseEvent.ROLL_OUT,onRollOutThumb);
//can.addEventListener(MouseEvent.CLICK,onRollOverThumb);
private function onRollOverThumb(event:MouseEvent):void
{
event.target.setStyle('borderColor','0x000000');
event.target.setStyle('borderThickness','3');
event.target.setStyle('borderStyle','solid');
}
private function onRollOutThumb(event:MouseEvent):void
{
event.target.setStyle('borderColor','0xCCCCCC');
event.target.setStyle('borderThickness','1');
event.target.setStyle('borderStyle','solid');
}
i hope some thing are clear in this, does n e one has worked on this, please reply
Thanks in advance

What about implementing a "flag" variable that is set to true when the click occurs. Then, when the ROLL_OUT occurs, check if the flag is true or false. If true, don't do anything, if false, remove/change the border.
private function onRollOverThumb(event:MouseEvent):void
{
if(event.type=='click')
{
for(var j:int=0;j<viewparent.numChildren;j++)
{
viewparent.getChildAt(j).name="false";
}
event.currentTarget.name="true";
for(var i:int=0;i<viewparent.numChildren;i++)
{
if(viewparent.getChildAt(i).name=="true")
{
Canvas(viewparent.getChildAt(i)).setStyle('borderColor','0x000000');
Canvas(viewparent.getChildAt(i)).setStyle('borderThickness','3');
Canvas(viewparent.getChildAt(i)).setStyle('borderStyle','solid');
}
else
{
Canvas(viewparent.getChildAt(i)).setStyle('borderColor','0xCCCCCC');
Canvas(viewparent.getChildAt(i)).setStyle('borderThickness','1');
Canvas(viewparent.getChildAt(i)).setStyle('borderStyle','solid');
}
}
}
else
{
event.currentTarget.setStyle('borderColor','0x000000');
event.currentTarget.setStyle('borderThickness','3');
event.currentTarget.setStyle('borderStyle','solid');
}
}
private function onRollOutThumb(event:MouseEvent):void
{
if(event.currentTarget.name=="false")
{
event.currentTarget.setStyle('borderColor','0xCCCCCC');
event.currentTarget.setStyle('borderThickness','1');
event.currentTarget.setStyle('borderStyle','solid');
}
}
i modified my own code, added one name property to the canvases
can.name="false"
and it's now working,
can n e one tell me, how to put some select and unselect(kind of fade effect) on the border, when the black selection get removed, it shld be removed in some fade manner, can we apply fade effect on border?
