I'm recently tried to make a custom tabcontrol that able to move the tab to left or right...
But there's a problem, I'm don't know how to get the tab's item width... What I get with TabControl1.SelectedTab.Bounds.Width is the tabpage's width, not tab item's width...
I need to get tab item's width to know if the selected tab had to be stay, or move left, or move right, when the mouse is moving and holding...
For an example, if the cursor pressed and holding Tabpage1, and it move to Tabpage2, then the Tabpage1 should be move right...
If I can get the tab item's width, then I can know the cursor is on which tab by mathematics... Or if can, I want to get the tab that on the cursor directly...
Maybe my question is weird, my code idea is silly, stupid or even crazy until you can't understand this question... If you have a better code idea, or answer for this question, then please reply...
Use TabControl.GetTabRect() to get the tab rectangle. Pass the index of the tab you are interesting in.

I've searched all the settings and Google but can find nothing. It seems such an obvious feature. If I use the arrow keys to scroll vertically through the code, I quickly end up with the cursor at the top or bottom of the screen whereas I really want to be doing my editing near the centre of the screen, which means I have to do two operations: scroll the code to where I want it and then move the cursor.
What I want is to hit a shortcut (e.g. the Scroll Lock key) and then when I press up- or down-arrow the cursor stays where it is (relative to the screen) and the code scrolls past it.
I've read that some tools allow you to set the number of "always visible" lines above and below the cursor which would do the job, but I can't find that in Rider either.
Am I missing something obvious, or is there an add-in or something I can customize to get what I want?
Found it! There are Move Up and Scroll and Move Down and Scroll actions in the keymap settings. Assign hotkeys to them (weren't assigned in my config) and it will work like you described it.
Problem solved!:
Just check the "Unified Title And Toolbar" option of the NSWindow and the 1pixel-down problem goes away!
To change the toolbar height just select the Toolbar Item - Custom View and change size in the Size inspector.
==============================
If you know Xcode 5s layout than you should recognise this:
I want to build it for my own. So I dragged a Toolbar in the Window and added a NSPopUpButton. Then I changed the PopUp Button Cell Style to Radio and turned off the Arrows. So far so good.
The first thing I noticed is that the Toolbars has different heights. Does anybody know how to change this behaviour (without subclassing NSToolbar)?
The second and more annoying thing I noticed is that if I choose an Item from the PopUp Button the Image for the NSMenuItem move 1 pixel down.
EDIT: Xcode NSMenuItems don't move 1pixel down
Any suggestions about that thing?
NSToolbar, sadly, can’t really be subclassed. It’s a poorly-written class that tries to be very “magic,” so it’s not even a subclass of NSView—you can’t control how it draws at all, it creates a private view.
You can set its “sizeMode” but I assume you’ve already done that and found that the number of pixels high isn’t what you want.
The easiest thing to do is just leave space for your widgets at the top of your window (above the document content) and have autolayout position your buttons for you. (I haven’t been able to use a real NSToolbar in years because of its limitations.)
As for the popUp menu being mis-aligned with the button: where the menu draws is basically hard-coded, so if you use a button style that NSPopUpButton doesn't expect then the menu will be offset some.
If you’ve already tried just unchecking the “draws border” flag on a default-style NSPopUpButton (one fresh off the palette), There are two solutions for to try: One is to keep trying different buttonStyles that look correct to your eye until you find one that’s not offset. Two is to leave the buttonStyle do the default for NSPopUpButtons but subclass the buttonCell and have it not draw the border (but still leave room for it).
I am designing a VBA UserForm (in Excel, if it is relevant) and I would like some controls to be visually grouped together.. but when I put them in a frame, I am getting some undesired results (part of it has to do with the RefEdit control which seems to be particularly unhappy inside a frame).
Is there a way to draw a border around a group of controls on a form without putting them inside a Frame?
Use a label with the caption deleted and the border style set to fmBorderStyleSingle. It may appear on top of your other controls, so right click on it and select "send backwards" until it's behind your other controls.
The best way to do this would be to create the shape over where you need it to be. Drag highlight everything that you want on top of it, then right click and brink it all forwards. Then when you drag your shape back over the top it will in fact be underneath everthing else.
Hope that helps.
This worked for me and I was at first having the same issue where I had to choose to "Send Backward" up to 30 times per label in some cases. I found that hitting the Ctrl-K sends it to the back of all controls with one time hitting these keys.
I have a UITableView with a navigation bar on top. I have several text fields in the cells and if i click in the cell at the bottom the keyboard hides the text field. So I googled and found this link: http://developer.apple.com/library/ios/#documentation/StringsTextFonts/Conceptual/TextAndWebiPhoneOS/KeyboardManagement/KeyboardManagement.html#//apple_ref/doc/uid/TP40009542-CH5-SW7
I used exactly that code and run my app again. Now it scrolls up (about the height of the keyboard) instead of scrolling down. Also it scrolls in every cell, even the cells at the top which will not get hided by the keyboard. Does anyone have a solution for this? I tried to log out some coordinates inside the keyWasShown: method but it's very complex for me to figure it out.
So I used trial and error and finally found out, that I have to add two superview properties behind activeField:
activeField.superview.superview.frame.origin
Do this behind every activeField in the method keyboardWasShown: and it will work. Ah and I added 70 pixels, because the view didn't scroll exactly where I wanted it to, maybe it is because of the navigation bar I use, I don't know:
activeField.superview.superview.frame.origin.y - kbSize.height + 70
I have a UIMenuController which I have added a few extra items to. I would like the menu to be BELOW the text that I select, so I tried:
[UIMenuController sharedMenuController].arrowDirection = UIMenuControllerArrowDown;
That seemed to do nothing, and everything I try, won't put the menu below the text.
How can I do that?
According to the docs, arrowDirection sets the direction the arrow points; it has nothing to do with the location of the menu relative to its target area. It also looks like they don't give you any control over the positioning of the menu beyond setTargetRect:inView.
If you really want to put the menu below the text, you might be able to set a "fake" target area and change the arrow direction to point to the "real" area of interest.
However, there's probably a reason Apple does it this way. My guess? If you select some text with your finger, your hand is probably obscuring the part of the screen below the text... so it's not very helpful if the menu appears there. Going out of your way to break consistency with standard UI conventions isn't usually worth the effort.
