remove the icon of the ListBox?

I am trying to remove the icon or image of the ListBox, but nothing seems to work? What I am doing wrong?

    var w = new Window ("window");
    lb = w.add ("listbox", [0,0,100,150], ["item1", "item2", "item3"]);
    var btn = w.add ("button");
    
    lb.items[1].icon = File ("~/Desktop/redSquare.jpg");
    
    // None of this is working... 
    btn.onClick = function (){
        lb.items[1].icon.remove();
        lb.items[1].image.remove();
        lb.items[1].remove("icon");
        lb.items[1].remove("image");
        lb.remove("image", items[1]);
        lb.remove("icon", items[1]);
        lb.remove(items[1].icon);
        lb.remove(items[1].image);
        }
    
    w.show();

Yes apparently once the item has an icon specified, you cannot "unspecify" it (lb.items [1] .icon = null; or lb.items [1] .icon = void (0); > error).

You can remove all items and re-create them with the necessary icons, or none.

Another possibility is to create an empty icon (completely transparent) the same size of the other:

var

f = new File ("" ~ / Desktop/redSquare.jpg ' ").

g = new file ("" ~ / Desktop/transparentSquare.png ' ").

w = (this instanceof Panel)? this: new window ('window'),

lb = w.add ("listbox", [0,0,100,150], ["item1", "item2", 'item3']),

BTN = w.add ('iconbutton', not defined, f, {style: 'toolbutton', toggle: true});

btn.onClick = function() {}

for (var k = 0; k)<3; k++)="" lb.items[k].icon="(this.value)" f="" :="">

};

BTN. Notify();

(o instanceof window)? w.Show (): w.layout.layout (true);

  • How can I remove the video from the independence of my departure to the top firefox and just get the icon of firefox?

    After updating to the latest firefox, 33 in my view, to start I initially get the firefox icon and then it immediately goes to video the independence of firefox (34 seconds). Its irritating and I can not seem to get rid of. Firefox icon shows and then is overllaid by this video. Help me get rid of it! Thank you!

    Here's how to 'fix '.
    Type of topic: config in the address bar and press ENTER. Accept the message of 'dragons' to see the Advanced preferences screen. Use the search box at the top to enter the below pref.

    You can assign an empty string to stop your Firefox to retrieve "extracts" and brandLogo changes the browser.aboutHomeSnippets.updateUrl pref. Right-click this pref and select Edit then clear the value as pref in the box that appears, and then click OK. Who will also disable "snippets" that appear under the container of the research on the default home page.

    Then you must open the folder of your profile, via help > Troubleshooting Information > profile folder > > folder view button. Then close Firefox.
    Your profile file open with Firefox closed (Firefox '3-bar' menu key > exit/Quit), wait two minutes, then remove the storage\moz-safe-about + House folder in the profile folder of Firefox to remove the brandLogo and stored in IndexedDB code snippets to make Firefox use the default brandLogo and a defined default code snippet.

    If you later change your mind about these changes, you can reset the pref browser.aboutHomeSnippets.updateUrl via the context menu and Reset allows to recover the default and start using the storage\moz-chest-fort-about + House file again.

  • Cannot remove the white icons next to bookmarks

    Recently updated to Firefox 3.x to 15 (I know, but 4 + is terrible IMO). Anyway - I want to delete the favicons next to bookmarks in the Bookmarks tab AND toolbar, and it doesn't seem to be possible. Currently they all display a vacuum instead of the icons themselves dotted box. It seems to do this fix for older versions (http://www.ghacks.net/2009/05/11/how-to-remove-favicons-in-firefox-bookmarks/) will remove the icon and keep the new to be added but will NOT remove this annoying box.

    I was on facebook and remove an icon by using the right-click menu, but then all my photos and pictures of profile, could no longer be seen. I was able to view them in the browser, so it's something I've done in Firefox. How can I unlock a site?

    If you select that right click menu context then you block all images from this area and not a specific image, so do not use that.

    • Check exceptions in tools > Options > content: Load Images > Exceptions (for example sphotos.ak.fbcdn.net)

    You can use the following steps to check if the images are blocked:

    • Click on the "More information" button to open the "Page Info" with the Security tab selected (also accessible via "tools > Page Info").
    • Go to the Media of the window tab "tools > Page Info.
    • Select the first link of the image and scroll down through the list with the arrow down.
    • If an image in the list is grayed out and there is a check mark in the box "block Images of..." and remove this mark to unlock the images from this area.

  • Remove the clicked point of Listbox (single column)

    Hello

    It seems a lot of posts on clear lines of the programmatically multicolumn listbox but not the only column listboxes.

    Woth the help of Martins and GerdW, helped me build a subset of a ListBox with items clicked in a reference list

    Make a table of items clicked in a list

    . How it adds a feature to delete just in case rather than the deletion of the entire list and do it all over again.

    Thanks in advance.

    Have an array of strings to the "REF" enter in the list box and store it on a shift register. When you remove an item (for example, for an event), remove this item from the list (using the removal of the table) and write back to the property Ref of the listbox. A single-column list box works exactly the same way as a multicolumn listbox.

    (Excuse the broken links to properties - what happens when you create an excerpt)

  • How can I remove the large green battery and plug icon?

    How can I remove the large green battery and plug icon? It seems pretty ugly and useless. There is already an icon of battery-plus-card used to determine the level of battery and charging status...

    Moderator edit: matched subject to content.

    Hi thang_nguyen!

    Another alternative is to double-click the battery icon and when Power Manager opens, click on Advanced Options > Options and uncheck the box "see the gauge of Power Manager in the bar then apply stains.

    To access the Lenovo Power Manager when the gauge of Power Manager is disabled, right-click on the Windows icon / energy from the battery in the bar of tasks and you should see "Power Manager".

    I hope this helps!
