I created and added a VCL frame to the component tools "templates" palette.
Now I want to remove it from the palette, but I can't find any info on how to do that.
Anyone know how to do that?
Click right mouse button on your template in 'Templates' page. You'll see popup menu with 'Delete "YourFrameClassName" button" item. Click it and you'll get what you want.
NOTE: Only works in DOCKED layout - see comments.

I have a TStringGrid, that has a TPopupMenu connected.
By clicking one event of the popup menu, I would like to get the calling component. Is that possible?
Background:
It is a bigger project, every form has a "BasicForm" I can inherited from. So I would like to provide a "default popup menu" for grids that have stuff like Copy, Select, and so on in it. In the inherited form I only match the grid (if exists) with that popup and I'm done.
Seems you are looking for the PopupComponent property of TPopupMenu:
Vcl.Menus.TPopupMenu.PopupComponent
Indicates the component that last displayed the popup menu in response
to a right mouse click.
Read PopupComponent to determine which control is currently using the
popup menu. In applications where multiple controls share the same
pop-up menu, use PopupComponent to determine which of them displayed
the menu.
Set PopupComponent to associate a control with the menu before calling
the Popup method programmatically to bring up the pop-up menu.
I assigned a popup menu to the TPageControl because I want to display it when I rightclick a tab.
So that works...
Unfortunately it also shows the popup menu when I right-click within the actual tab sheet.
This I do not want because my ListBox1 in the tab sheet responds to a right-click to execute some code.
So right now it's a mess, the code fires upon rightclick of the listbox but also then displays a popup menu.
How can I nullify this popup menu in the tabsheet or at least within the listbox itself?
ok, Handled := True; was all that was needed in the popup event of the listbox. Thanks Rufo for pointing me in the right direction.
How can I make an edit control in fmx transparent and at the same time hide the borders of the control, so it will blend into the control in the back?
What I am trying to do is to make a small Notes program where, when I double-click a tabitem, it shows an edit control to change the text of the tabitem.
Right click the edit control (let's say Edit1) and click 'Edit Custom Style'.
Expand 'edit1style1'.
Click background:TActiveStyleObject.
Clear the SourceLookup property.
I've got a TMemo with an associated TPopupMenu on a FireMonkey form.
When I rightclick on the memo, I get my own popup menu, but after my popup disappears I still get the default popup (the one that says cut, copy, paste, select all).
How do I disable the default menu, or can I add my own items to the default menu perhaps?
I can't reproduce this behavior. Here's what I tried:
File->New->FireMonkey HD Application
Drop a TMemo and TPopupMenu on the form
Assign PopupMenu to Memo1.PopupMenu in the Object Inspector
Create two menu items in the PopupMenu, and assign them both the same OnClick event (generated in the Object Inspector). I left the default caption of MenuItem1 and MenuItem2 in the Caption of both items.
Wrote a simple MessageDlg that displays TMenuItem(Sender).Caption with a single Ok button in the OnClick handler.
Run the application, right-click Memo1, and choose either menu item
I get a single menu displayed with my two items (MenuItem1 and MenuItem2). Choosing either item displays the appropriate Caption in a message dialog, and clicking Ok in that dialog. There is no default popup menu displayed.
EDIT: Found it for you. This is a bug fixed in Update 3 - see the list of bug fixes in Update 3, and search for 98705, or scroll through until you reach the section on FireMonkey\Components (it's the second or third entry under that section).
You know how in a popup menu if you click outside of the menu the popup disappears? Well I would like to reproduce that.
Currently I am having a panel created with some components on it when a button is clicked. The panel and sub components go away when you click a certain button on the panel. However I want it to go away if you click anywhere outside of the panel.
I think you would need to install and application-wide mouse message hook, and if your panel is visible and the coordinates of the mouse event are outside of your panel bounds, then hide the panel. Also handle the WM_ACTIVATE message in your form.
[Edited: removed answer involving SetCaptureControl() because the bahaviour is not appropriate in this circumstance]
