In Lazarus, once you undecorate a form, how do you decorate the form again. To Undecorate, all you do is right click on the form's title bar on the top. Then, click on Un/Decorate option. At that point title bar disappears. Now, how do you undo or decorate again? There seems to be no option anywhere in the Lazarus IDE that I can see.
While I'm not familiar with this method of "undecorating" a form, the way you can specify whether a form has a title bar is through the form's BorderStyle property. Select the form in the object inspector and set the form's BorderStyle to bsNone to cause the form to be displayed (when the program is running) with no border or title bar. Setting it back to bsSizeable will cause the form to have a normal border and title bar. There are other options you can try that affect whether the form is sizeable and the type of borders it has.
These options may have slightly different meanings on different platforms under different widget sets.

I'm currently working on a project that utilizes an MDI Form. What I would like to achieve is that when the user hovers over one of the menu options in the MDI menu, a ToolTipText appears describing what can be found in said menu. I'm aware of the fact that in some options for VisualBasic 6, ToolTip is supported. However, I can't seem to add this to the MDI Form, or add a label control for that matter. Has anyone ever run into this problem, and if so, is there a workaround or a solution?
Please let me know if you have any additional questions or comments. Thank you in advance.
I'm not aware that any true menus on a VB6 for (even non-MDI) have a tool-tip property; hence, neither does the MDIForm when one its child forms has its menu displayed.
However, there are a few controls that can be put on the MDI parent form. The most useful of these is probably the PictureBox, into which you can then place any type of control, such as CommandButtons. It must be "docked" to either the top or bottom of the MDIForm, using the PictureBox.Align property. Controls within the PictureBox can be located any way you wish, and can have their normal ToolTip properties set.
Another MIDForm-usable control that I've had good luck with is the ToolBar control, which comes in as part of the CommonControls component. Like the PictureBox, it has a .Align property to set it to the top or bottom of the MDIForm. You can put any reasonable number of "buttons" on it, and have reasonable control over their appearance (graphics, etc.); apropos the OP's query, you can assign a ToolTip to each button. It wouldn't be difficult to have the buttons change depending upon the currently-active form, just as the MDI menus normally do.
One other alternative that can be considered (but may be quite tedious to implement) could be reading the Mouse.X and Mouse.Y properties for each MDI menu and setting the captions of a Label control (or TextBox) using the Mouse Hover event.
You'd need to find the top left and bottom right points for each MDI menu and if it is within the box, you can show your label control with the intended caption. But note that you can't just put any controls on an MDI Form except maybe PictureBoxes, Toolbars and Coolbars, etc.
So the Label or TextBox control would have to be first placed on top of a PictureBox control which can be top aligned.
I have a view with a lot of UI buttons. I want some of the buttons to show and some to be hidden depending on my dynamic content. This can be done with button.isHidden = true. The problem is that the layout still set its constraints to the hidden buttons which create a lot of empty space.
You can see the empty space at the bottom in the picture where the buttons are hidden. So, is it possible to make the buttons "gone" instead of hidden? In Android Studio there is a isGone code (can't remember the exact code) that not only hides the button but removes the height and width of it as well.
I'd like a toolbar button with an attached dropdown menu, like the "Flag" button in the toolbar in Mail.app:
I'd hoped that making a normal NSMenuItem and adding a menu as the menuFormRepresentation would do the trick, but that menu only appears when the button goes into overflow mode.
I had also hoped that adding an NSPopupButton as a custom view would work, but that makes the whole view a menu, whereas I want the left part of the component to behave like a normal button, and the right dropdown part bring up the menu.
Is there some trick to making the NSToolbarItem show a component like this, or is this two custom views stuck together?
There's nothing magical about NSToolbar here. That's just one of the ways you can set up NSSegmentedControl, regardless of whether it appears as a toolbar item's custom view or on its own.
You can't set this up in Interface Builder (storyboard), but NSSegmentedControl has APIs for assigning menus to segments:
segmentControl.setMenu(myMenu, forSegment: 1)
segmentControl.setShowsMenuIndicator(true, forSegment: 1) // for the little arrow
You probably want to set the tracking mode to momentary, since your segment control is acting as a set of visually-connected buttons, not a choose-one-of-N selector.
When the user clicks either segment, your action method will need to use the selectedSegment to decide whether to perform the action associated with the "button" side or ignore the click (letting the menu show for the other side).
I have a bunch of buttons. They appears as an graphical image. If a user clicked on a button I can determine with
sender.titleLabel!.text!
which button the user pressed. But the title of the button appears in the view. I want only to show the image and give the button a invisible title. But I think that is not possible.
Me second solution is to create for each button an outlet. But I think with 30 buttons that is a very bad solution.
Option 1:
For the button text color property set opacity to 0. The text is there, but fully transparent.
Option 2:
You may use the tag value to identify a button so you do not have to rely on the button title. You can set the tag value in interface builder (Xcode) or in code. (The tag is an integer.)
I usually prefer option 2 as it is resilient to text changes over time (think of typos, translations for other languages etc.).
I have a page with a couple of widgets on it, each of which, when clicked, brings up a yui popup menu: If I click on widget 1, its menu comes up. If I now click on widget 2, widget 1's menu gets a hide event, and widget 2's menu gets a show event and comes up. I'd like to change this so that, when widget 1's menu is up, it must be explicitly dismissed by a click on the page background (and/or, perhaps, another click on the widget or the escape key) before the menu attached to widget 2 is allowed to appear.
I've set up some beforeShowEvent and beforeHideEvent handlers on the menus, hoping to be able to use some method (a global variable? ick) of keeping track of when a menu is present and showing or hiding accordingly, but it's not working -- these handlers can't tell the difference between a click on the page background and a click on widget 2 (at least, not as I've done it so far). Is there any way to do what I'm trying to do? Thanks!
I think that a combination of clicktohide: false
Boolean indicating if the Menu will automatically be hidden if the user clicks outside of it. This property is only applied when the "position" configuration property is set to dynamic and is automatically applied to all submenus.
and keepopen: true
Boolean indicating if the menu should remain open when clicked.
will take care of this.
