I am making a custom menu. I am applying colors on panels on mouse enter and mouse leave.
I have labels on these panels, and the mouse enter and leave events work snappy, but as soon as I hover over the label (on/inside) the panel, the mouse leave event is fired. I know I can just do the same thing for the label mouse enter event, but I am doing some other visual stuff, and I need to have the label mouse events totally disregarded. Any ideas?
Thanks in advance.
I eventually just used the menu control, and styled it accordingly. Does the job better than I could with code...

I have multiple buttons in a Panel. I want to hide the Panel on mouse leave of the panel, or buttons.
The problem is that when my cursor hovers on one button and hovers again on another button, the panel that holds the button will hide because I have panel.hide() code on each mouse_Leave event in the button and on the panel. I want to hide it when the cursor leaves the panel or the button.
It sounds like you basically want the panel hidden at all times unless the cursor is over it, and when the cursor isn't the panel hides again?
You could try keeping the panel hidden by default so it's always that way unless the mouse enter's over it, then it shows. That way, when the mouse leaves the panel again it'll automatically hide.
i have developed custom control which inherits Button control, actually i`m creating button with one picturebox and label on Button(picturebox and label are child controls). I created same method and wired child controls to behave as clicking on parent(Button), it works but its slow no mather what i do(tried with InvokeOnClick, me.performclick, Me.OnClick(New EventArgs()), tried with same method for all events), but clicking on label or picture box is slow, i need it to be fast as clicking directly on button cause in my application is very important to be able to click on button twice in second for example, if you click on label or picturebox twice at second it will fire just one time not 2.
What i have been thinking of is to make label and picturebox invisible for event is it possible or anyother idea ?
Thanks in forward
You are doing battle with ControlStyles.StandardDoubleClick. Which is turned on for the PictureBox and Label controls but turned off for Button.
So when you are clicking rapidly on either the picturebox or the label then they'll generate the DoubleClick event instead of the Click event. You'll interpret that as "slow" since you probably didn't write a handler for that event. Subscribing the event and calling Me.OnClick is a workaround.
Just don't do this. PictureBox and Label are point-and-click convenience controls but they are extraordinarily wasteful. It takes just two lines of code in the button's OnPaint() method override to get the exact same outcome, minus the overhead and the event problems. Use e.Graphics.DrawImage() to draw the pb's image and TextRenderer.DrawText() to draw the label's text.
Using MouseDown event ensures the event is triggered once per click, regardless of click/doubleclick.
I have a tabpage. And I have a combobox in it.
When I hover my mouse over it, my tabpage's paint function runs.
Why?
The Combobox has no functions handled. It is just a Combobox.
I move the combobox out of the tabpage, and now the tabpage won't paint when I hover my mouse over the combobox. Weird..
This isn't specific to a TabPage, the same thing happens when you put the combo on a form. It is affected by visual styles, the container paint requests stop when you turn that off. I'm guessing it has something to do with the rounded corners you get when the DropDown property is set to DropDownList, the combo glows on a mouse hover. With it probably asking the container control to draw the pixels in the corner. Explaining it for DropDown = DropDown is harder.
Same thing happens with a Button, the container control paint is documented in the Reference Source to support transparency effects. Even if the button doesn't have anything transparent. Visual styles is less than optimized like this, perhaps. It is otherwise very similar to what WPF does. Long story short, this is normal.
As the question is asked ... how can i prevent that from happening?
I have ZOOM IN and ZOOM OUT button that receive focus after pressed.
The button in CF does not have focus property so im guessing im required to do another painful workaround...
Any ideas?
This is the way the system draws the buttons when clicked. If you don't want this you'll have to redraw the button (and it various states) yourself
I am developping a Cocoa application and I have a special need. In my main window, when I mouse down on a certain area, a new window (like a complex tooltip) appears. I want to be able to do:
- mouse down on the main window (mouse button stay pressed)
- user moves the mouse on the "tooltip" window and mouseup on it.
My issue is that the tooltip window does nto get any mousevent until the mouseup.
How can I fix this?
Thanks in advance for your help,
Regards,
And it won't since mouse is tracked by the main window. However, you can process mouseUp in the main window, transform click coordinates into the desktop space, get tooltip window frame and check whether the click occurred on the tooltip. After that, you can send a message to the tooltip window manually.
Or you can try to find another way to implement the final goal :) It is usually better to follow the rules, in this case - mouse tracking.
