In JavaFX WebView I can view view html pages. Although shortcut to find a word doesn't work there (Ctrl+F).
How can I enable Ctrl+F functionality?
WebView does not support this functionality.
I raised a feature request for it. The feature is not scheduled for implementation. You can vote for it if you like.
You can implement the find functionality yourself.
An example would be to create a new HBox in your FX scene that opens when it detects the CTRL+F event with a TextField for typing into. After this, you'll need to make it so that every time you type in the TextField it will fire off an event to a method where you implement some Javascript that searches through the DOM of your current page based on what you typed in to find. You can also make it so that your script highlights the word it found, amongst other find related tasks.

I am working on text editor app and using UITextView for this. Does anybody know how to make ability to do bullet/num/check lists in it? Any examples/tutorials?
Note: I need to do this as a part of text editor, so user can select some area, tap on according button and enable/disable lists formatting.
Based on my research for similar behavior (e.g. Bullet list and Numbered list in UITextView ), I would expect that there is no easy way to do it. I expect that you will have to use textView(_:shouldChangeTextIn:replacementText:) to hack currently added text to manually add bullets/numbers - e.g., if the user set that she currently wants to use unordered list, you will have to detect a new line added in shouldChangeTextIn and manually add there the bullet and indentation.
Another approach which you might consider (its applicability depends on your requirements) is to customize existing open source rich text editor. In my case I was able to get close enough to what I needed using RichEditorView, which uses HTML+CSS as an underlying technology (so to be able to do customizations, you need to know a bit about JavaScript, CSS and HTML).
I'm trying to set up automatically focus on first loaded article. (f.e. user clicks on the button "load more" and new articles are loaded).
My react implementation:
I'm using ref attribute in <Link> component, which is from react-router library and then I'm calling focus() method in lifecycle method componentDidMount().
It works on all devices except iOS. If I turn on voiceover on iphone and then on webpage I click on the button, it doesn't automatically focus on first loaded article). It works just with html anchor tag.
I read some articles before and it looks that it's not possible to do this in this way but only with firing some event f.e. click event.
Can someone confirm that it's not possible to solve it in this way or there is any workaround without using jquery ?
I am developing a jQuery Mobile application that will run into a Cordova wrapper.
I am struggling to understand the use of each pagecontainerX event and when to use which.
I will post three specific use cases:
1) hook click events:
Say I want to assign a handler to a certain click event on a button.
2) change textual content of the page:
Say I have a page and I want to update some content that might have changed since last time I have shown the page.
3) change graphical content of the page:
Like if I want to draw on some canvas, or in cases where I need to know how things are rendered and their size.
Preliminary answers:
these is what I have found myself, but I would really much appreciate comments:
1) I am using the pagecreate event, as it's only called once. It is also possible to specify what specific page you want to hook the handler to by doing: $(document).on("pagecreate", "#pageid", handler);
2) I am using pagecontainerbeforetransition or pagecontainerbeforehide. Pagecontainerbeforehide has the advantage that is only fired once, while the other is fired twice (dunno why). Other options, like pagecontainershow, will change the content after transition, which is a bit weird to look at.
3) In this case I am employing pagecontainershow, so that things have already been graphically rendered and I can compute heights and widths etc., the drawback is that the user will see the transition, and only after he will see the content of the page being modified.
I'm trying to activate Hint from control of different application created from delphi upon focus, I'm using hook to identify the focused control, and then use WM_MOUSEMOVE, which I think will activate the Hint of that control, the handle would be the Control itself and the lParam is the Left and Top of the Control. The Control activate the OnMouseMove Event, but the Hint never shows. but when I use SetCursorPos, Hint show, but I need to show the Hint with out the cursor move on that Control. Can you please help me with this? Thank you in advance... by the way I'm using Delphi XE4
Among the really asked question is how to show the hint of a control that resides on another application (i am afraid without hook that application can not be done), the title is "Delphi - Activating the Hint from another control of Application".
First is first: That can be done without knowing what language the other app was done, but it is very complex to put it here (and i am not an expert on such way of coding, also i hate apps that work that way).
Second: The main idea is to hook the other application, search on Google some code of that apps, that can show you a rectangular hole square of the object the mouse is passing over, that application while doing it is iconized (i do not remember the name of it).
Waht such app does: As you move the mouse over the screen it overlays a rectangular over the control that mouse is over, then if you press the key to print screen, that small region is the only thing that goes to clipboard; on of such apps i saw had an extra funcion, they can move such controls if you press cursors on keyboard, also can hide/enable/disable such control... more, it can also make controls that are invisible to be visible, etc... i saw it working on my computer, and hey, for fun it is pretty and to DeBug or get extra things on some apps is also great (make some menús to be visible and enabled and then can use such funtions).
Please, please, understand i am agaist piracy and also against using such apps to let code to be run... some apps need pay for letting some menus enabled, but they have the code there, no need to change EXE to have/use that menus; just using this kind of apps makes that limited apps to be unlimited (just enable or show hidden menus and voila).
Note: To unhide menus, mouse point is not needed to be over the app, can be anywhere and is not moved.
The idea i want to say is: Any app can move, alter any control on any other app (at least on Windows) that is running, so maybe there can be a way to show such hint.
In the past i had use such app (sorry i do not remember the name) for DeBug my own apps, so i do not need to recompile in such cases where something was wrongly hidden, also work with buttons, labels, texts, combos, memos, etc.
Now my small problem is: I just need exactly what title say, but i can not make it to work.
Must be:
Mouse position must be irrelevant (it also must be able to be outside the application)
Just when a button that has focus is pressed with keyboard (Space or Enter) or just after some code somewhere on my application, i want to show the Hint of a specific TEdit for a short period of time.
I did not get Hint to be shown; not unless mouse point is over such TEdit but i want/need mouse pointer to not be over it, neither it to jump to the TEdit.
Idea Conept for that Hint to be shown: After doing some code that changes something, show extra info associated.
Example:
A button with that loads a file using an open dialog, filename is put on a ReadOnly TEdit (so it let user copy the text, but not change it); i want extra info that i punt on .Hint of such TEdit to be shown inmediatly.
That hint use is for not overload window with a lot of fields (TLabels) for showing such file data.
Simple idea: such Hint shows TimeStamp and size of the selected file.
P.D.: Not much related (since i am trying with a normal plain text hint), but hints can also store a full HTML page and with 3rd party tools be shown as an HTMLhint, so they can show a lot info of that file (also its content, etc) in a web based format; as i say i first try with standard plain text hints.
In order to show hint programatically you need to call TApplications ActivateHint method to which you specify the position parameter.
http://docwiki.embarcadero.com/Libraries/XE3/en/Vcl.Forms.TApplication.ActivateHint
Based on position parameter Application automatically finds which controll is at that position and shows its hint.
NOTE: Position parameter screen coordinates in pixels and not your controll coordinates. So you will have to use ClientToScreen method to change your coordinates apropriately.
You can see simple example of how to use this here: https://stackoverflow.com/a/15031208/3636228
Now if you need to do this from another application then you will have to add some comunication mechanizm to these two application so that one could send a proper message to tell the other to show the hint at specific position. But this does require you to be able to change both applications.
EDIT: This works with VCL applications but I'm not sure if it would work with FireMonkey applications.
Background/Context:
I am developing touch screen based kiosk application with JavaFX. The app integrates browser – WebView. The problem is that all user inputs have to be made through on screen keyboard (SW keyboard)
It would be nice to have an option to register an event-handler on WebView/WebEngine for any HTML text input element got/lost focus, so that I could show/hide on-screen-keyboard.
Even though I searched the Internet, I did not find this kind of feature.
My questions:
Does JavaFX / WebView provides any support for these cases?
If you were to tackle this problem, what would be your approach to that?
My solution so far:
I have a small button (at one corner of the screen) that allows user to show/hide on-screen-keyboard. Since they have to do that manually, it is quite annoying. Especially on sites where browsing (consuming information) and text inputs changes frequently.
It would be nice to have an option to register an event-handler on WebView/WebEngine for any HTML text input element got/lost focus, so that I could show/hide on-screen-keyboard.
A potential strategy for doing this:
Start with a jdk8 preview.
Run the application with -Dcom.sun.javafx.isEmbedded=true to enable the virtual keyboard.
Use a webengine.executeScript technique to embed jQuery into the target page.
Bind a jQuery focus handler to the relevant html elements.
In the jQuery focus handler make an Upcall from JavaScript to Java.
Upon receiving the upcall make use of JavaFX's Virtual Keyboard.
As the user enters values into the keyboard, make executeScript calls to set the value of the corresponding html field.
Some parts will likely be a bit (or totally) flaky, but perhaps other parts may prove useful to you.
In the future, if WebView is supported on touchscreen platforms on embedded devices, I'm guessing that out of the box it will work well with a virtual keyboard.
