Trigger checkbutton hover event from another widget

Asked 2021-May-28 at 10:46

I made a custom Right-to-Left check button widget using a Gtk::CheckButton without the label and a Gtk::Label inside Gtk::EventBox.

The reason I went this way instead of simply calling set_direction(Gtk::TEXT_DIR_RTL) is that I want to manually specify the alignment for these widgets.

I've figured out activating/deactivating checkbutton state when the label's clicked but I'm having trouble triggering the hover event from label to checkbutton. The default Gtk::CheckButton behavior triggers the hover effect on the clickable square button to indicate it's being activated when text is hovered too. How do I achieve that same behavior on my custom right-to-left checkbutton widget?

Below is the minimal reproducible code for testing:

ANSWER

One way is to use set_state_flags() and trick the visual output of your Right-to-Left checkbutton when the label is being hovered.

First, you need to enable these two masks for eventbox to capture enter and leave event:

Gdk::ENTER_NOTIFY_MASK
Gdk::LEAVE_NOTIFY_MASK

QUESTION

can I calculate the value of CSS property of a dynamically changing div and use to calc() the value for positioning a sibling div in CSS?

Asked 2020-Jul-17 at 12:01

So this is what I am trying to do. There is an element/div which has some sibling div related to it like a modal. I know the size of the element div and have manually adjusted the transform property of the modal to be close to element but not overlapping and within the screen using the translate() function. What I intend to do.

calculate the size of the elementbox and modal and calculate the transform parameters for the modal dynamically. I need to be able to pass the height and width property values of the elementbox to the modal class to fulfill that. 2)determine the position of the element box in the viewport (I have thought to divide viewport into four quadrants). Decide the direction of transformation of modal on the basis of it.

{elementbox quadrant : modal transform direction}

Note: Javascript solutions are welcome but I need to know if this is achievable by CSS only? Also the con of Javascript is if user resizes the window in this case I need another eventlistener for this.

Simply, no. CSS alone will not be able to determine the position of an element in order to style an element. You will indeed need a dynamic solution using JS for this.

It sounds like you are writing your own tooltip library for your application. If this is the case, I recommend considering third-party solutions for this as they already have done much of the heavy lifting an often already address accessibility needs. Some I found, though have not used myself:

Tippy.js
Popper.js
or if you're already using a UI toolkit, check if it is already built in. For example, Bootstrap already uses popper.js for this.

If you are determined to write your own JS for this you are correct in that you will need a resize event listener. Be sure to use a debounce function for this so you don't encounter performance problems.

What are the gtk 3 python constants for the scroll events

I've been searching for the constants for python gtk 3 using PYGObjects. Specifically what are the enum constants for the scroll events. 'gi.repository.Gdk' object has no attribute 'SCROLL_UP'.

Pass style as props in react component

I created a event-box component in react. What I want is whenever is it called, I passed color values as props which later get used to set its border. Currently, I set two hardcoded class names and passed them as props with the component. Is there any other way to do so as I won't able to add all the color class names in my stylesheet.

Does Python have a "pointer" equivalent for the purposes of PyGObject?

Asked 2020-Apr-10 at 03:32

I am trying to use Gtk.SelectionData.set, for which one parameter is

data (bytes) – pointer to the data (will be copied)

The data I want to pass is a Gtk.EventBox, but I am unclear on how to create a pointer to this data, or whether I even should. The documentation for GObject's Python bindings is automatically generated from the C documentation, and as far as I've been able to find, Python doesn't have a direct equivalent to pointers in C.

I cannot find any examples of this function being used in Python code. I've found examples in C, such as

ANSWER

Answered 2020-Apr-10 at 03:32

It's not going to be possible to translate that example directly to Python, because, even if you could get the address of the event box to store in the clipboard, unlike in C, you would not be able to reconstitute the event box object out of the address on the other side.

It would be hard to suggest what to do instead without knowing more about your particular application, but maybe you could store a textual representation of how to get to the widget from the top level, something like event_box.get_path().to_string()?

Gtk.EventBox

The Gtk.EventBox widget is a subclass of Gtk.Bin which also has its own window. It is useful since it allows you to catch events for widgets which do not have their own window.
Gtk.Widget.add_events(events)

Adds the events in the bitfield events to the event mask for self.
Gdk.EventMask
A set of bit-flags to indicate which events a window is to receive.
- GDK_MOTION_NOTIFY the pointer (usually a mouse) has moved

The Gtk.EventBox should have got the flag, not the window!

How can I draw a rectangle over a widget without stealing its events?

Asked 2019-Jul-29 at 11:24

I'm trying to implement a custom docking solution using a Gtk.DrawingArea placed upon a Gtk.Overlay, but when I attempt to show the Gtk.DrawingArea during a widget's drag_motion event it triggers the drag_leave event. The problem here is that I'm using the drag_leave event to hide the overlay, which means that I'm just toggling between visibility states as the cursor is moving. How can I prevent the overlay from triggering the bottom widget's drag_leave event after it has been made visible?

Also, is there a more efficient way to approach docking? Should I be using Gtk.Window instead of Gtk.DrawingArea? What is the best way to draw a simple rectangle over a region and have it move when an item is dragged?

I've tried using a Gtk.EventBox instead of a Gtk.DrawingArea
I've tried using a Gtk.Window with Gtk.WindowType.POPUP instead of a Gtk.Overlay
I've tried using GDL but I would prefer to create my own widgets using vala
I've tried calling gtk_overlay_set_overlay_pass_through
I've tried calling gdk_window_set_pass_through

ANSWER

Answered 2019-Jul-27 at 15:56

I guess the right answer might depend on exactly what kind of effect you're looking for.

You could render the source widget to a pixbuf and call Gtk.drag_source_set_icon_pixbuf()1 to set that to be dragged around.

You could try unparenting the source widget from its existing container and add re-adding it to the overlay, then use absolute positioning to move the whole widget.

Or it might just be easier to use the existing dock widgets in libdazzle.

Apologies for lack of concrete suggestions!
