In Delphi XE, I use the rename variable refactoring (Ctrl+Shift+E) a lot of the time to make my code easier to understand by giving more meaningful variable names, for example:
That is all good but I have one slight issue regarding workspace when I use this. I like to keep the code messages etc pinned to the bottom, they only appear when I hover my mouse over them - this is my preference to allow more space for the editor.
Now, when I use the rename variable refactoring, the dialog has the checkbox: View references before refactoring as shown from the image above. I have this unchecked as I generally don't need to oversee what is been changed etc, if needs be I just undo it.
Here is my issue, with that unchecked I would of hoped for the refactoring to of performed silently, but no I still get the refactorings window showing up underneath:
It might not be considered a major issue but every time I have to manually close the refactorings window is just wasting time and is becoming a nuisance.
I noticed if you click on the refactorings tab in the editor there is an option to hide, but this is not permanent as it will come back the next time you refactor anyway.
Is there an option I may have missed somewhere to prevent the refactorings window from displaying in the code editor?
…to prevent the refactorings window from displaying in the code editor
How about moving it elsewhere? Undock it from the bottom of the editor window and dock it at a different place. (Unless you've hidden all the side panels.)

I'm trying to activate Hint from control of different application created from delphi upon focus, I'm using hook to identify the focused control, and then use WM_MOUSEMOVE, which I think will activate the Hint of that control, the handle would be the Control itself and the lParam is the Left and Top of the Control. The Control activate the OnMouseMove Event, but the Hint never shows. but when I use SetCursorPos, Hint show, but I need to show the Hint with out the cursor move on that Control. Can you please help me with this? Thank you in advance... by the way I'm using Delphi XE4
Among the really asked question is how to show the hint of a control that resides on another application (i am afraid without hook that application can not be done), the title is "Delphi - Activating the Hint from another control of Application".
First is first: That can be done without knowing what language the other app was done, but it is very complex to put it here (and i am not an expert on such way of coding, also i hate apps that work that way).
Second: The main idea is to hook the other application, search on Google some code of that apps, that can show you a rectangular hole square of the object the mouse is passing over, that application while doing it is iconized (i do not remember the name of it).
Waht such app does: As you move the mouse over the screen it overlays a rectangular over the control that mouse is over, then if you press the key to print screen, that small region is the only thing that goes to clipboard; on of such apps i saw had an extra funcion, they can move such controls if you press cursors on keyboard, also can hide/enable/disable such control... more, it can also make controls that are invisible to be visible, etc... i saw it working on my computer, and hey, for fun it is pretty and to DeBug or get extra things on some apps is also great (make some menús to be visible and enabled and then can use such funtions).
Please, please, understand i am agaist piracy and also against using such apps to let code to be run... some apps need pay for letting some menus enabled, but they have the code there, no need to change EXE to have/use that menus; just using this kind of apps makes that limited apps to be unlimited (just enable or show hidden menus and voila).
Note: To unhide menus, mouse point is not needed to be over the app, can be anywhere and is not moved.
The idea i want to say is: Any app can move, alter any control on any other app (at least on Windows) that is running, so maybe there can be a way to show such hint.
In the past i had use such app (sorry i do not remember the name) for DeBug my own apps, so i do not need to recompile in such cases where something was wrongly hidden, also work with buttons, labels, texts, combos, memos, etc.
Now my small problem is: I just need exactly what title say, but i can not make it to work.
Must be:
Mouse position must be irrelevant (it also must be able to be outside the application)
Just when a button that has focus is pressed with keyboard (Space or Enter) or just after some code somewhere on my application, i want to show the Hint of a specific TEdit for a short period of time.
I did not get Hint to be shown; not unless mouse point is over such TEdit but i want/need mouse pointer to not be over it, neither it to jump to the TEdit.
Idea Conept for that Hint to be shown: After doing some code that changes something, show extra info associated.
Example:
A button with that loads a file using an open dialog, filename is put on a ReadOnly TEdit (so it let user copy the text, but not change it); i want extra info that i punt on .Hint of such TEdit to be shown inmediatly.
That hint use is for not overload window with a lot of fields (TLabels) for showing such file data.
Simple idea: such Hint shows TimeStamp and size of the selected file.
P.D.: Not much related (since i am trying with a normal plain text hint), but hints can also store a full HTML page and with 3rd party tools be shown as an HTMLhint, so they can show a lot info of that file (also its content, etc) in a web based format; as i say i first try with standard plain text hints.
In order to show hint programatically you need to call TApplications ActivateHint method to which you specify the position parameter.
http://docwiki.embarcadero.com/Libraries/XE3/en/Vcl.Forms.TApplication.ActivateHint
Based on position parameter Application automatically finds which controll is at that position and shows its hint.
NOTE: Position parameter screen coordinates in pixels and not your controll coordinates. So you will have to use ClientToScreen method to change your coordinates apropriately.
You can see simple example of how to use this here: https://stackoverflow.com/a/15031208/3636228
Now if you need to do this from another application then you will have to add some comunication mechanizm to these two application so that one could send a proper message to tell the other to show the hint at specific position. But this does require you to be able to change both applications.
EDIT: This works with VCL applications but I'm not sure if it would work with FireMonkey applications.
I have a lot of files to keep open, and the current single line of tabs is just difficult. I see that GExperts and CNPack does not have that (unless I missed that).
Is there any trick to achieve that, or any other suggestion that I could have more tabs visible?
The TIDEGradientTabSet (if it's still used in modern Delphi) doesn't support multiline view, so the only option for those IDE experts could be making own tab set control hiding the original one.
Alternatives are:
On the far right of the tabs is a small down arrow. Press that, and you'll see a list of all the files that are open in the editor;
Pressing Ctrl+B will open up a dialog to select a tab;
TMS has a free tool AltTab but it did not get update for while. That was exactly what was needed for Delphi IDE;
I have an interesting observation and question, but first a comment. I have been using Delphi for 14 years and have taken a job developing an iOS mobile application using XE5. This is my first time using FMX and frankly I feel like I am stepping back in time many moons ago. In other words, if this is the future, then it feels like I have crippled. No problem though. Roll with the punches. Developing in this brave new world is not just a job. It is an adventure.
Now my question. Start a FMX mobile project using the "Header/Footer with Navigation" as your base. Then add an edit control (Edit1) to the first tab item. Then set the tab control align to none and move it to the right until you can clearly see the form itself. Then add an edit control (Edit2) to the form.
Now set the form's active control to Edit1 and run the app - no focus on Edit1. Now set the form's active control to Edit2 and run the app - focus is placed on Edit2. Interesting. Tab is a foreign word to tablets, right? Why have active control or even setfocus available? Is this an oversight by Embarcadero? Any thoughts?
Long story short I think they both have potential uses.
I use the SetFocus call to manually show the keyboard. Lets say the user navigates to a page where they're 100% sure to be putting in their username (or any text), I'll use ctrl.SetFocus to show the keyboard just to save them having to click (or is it press now?) on the edit.
I don't see ActiveControl being as useful, but it could definitely still be used. You could possibly use it to set up some sort of tabbing like structure for when the user presses Next on the keyboard (when the edit's ReturnKeyType is rkNext).
I'm new to Delphi and I've found some strange behaviors of Rad Studio XE3 code editor.
E.g., when i press the undo shortcut (Ctrl+Z), the editor does not undo just the last code editing, but also latest caret movements. I mean: when I open a unit and I browse through its code, it happens that I go clicking around, without editing the code. Well, if I press Ctrl+Z, the caret will move back to all points where I've been clicking before. I was expecting nothing to happen when I press Ctrl+Z, if no edit was performed!
There is a way to deactivate this feature?
I've CnWizards_1.0.0.638 installed.
Thanks.
You cannot disable that behavior completely, but you can reduce its effect. Turn on the group undo editor option. Then all consecutive cursor movements will be grouped into a single action. Other types of consecutive actions will be grouped together, too, but I don't recall that being an issue for me.
Moving the caret when performing undo of edit actions is very much by design. This is for sure not strange behaviour and all editors behave this way.
If the caret was not moved, and the window now scrolled, you would have absolutely no feedback that an undo event had occurred. For instance, the edit that you undo could perhaps be in code that is not currently visible. For sure in plain Delphi there is no way to change the behaviour and I'd be astounded if any plugin offered such functionality because it would render the undo functionality completely unusable.
Perhaps what you want to do is to undo some changes, and then return to where you were in the edit window before performing the undo operations. Well, the way to achieve that is to drop a bookmark, perform the undo, and then jump to the bookmark.
i have a flow panel that i'm adding extra items to it at runtime based on whether they have chosen to show all the items. that's all works fine; the expansion is controlled by a toolbar button.
the trouble is we'd like the user to be able to move his mouse over the "+" sign to expand the section.
initially i looked at TSpeedButton (OnMouseEnter) but even when it's "Flat", the focus rectangle still shows and so the glyph isn't centered. the main problem with this solution is it's appearance.
then i looked at making a descendant of TImage. that's a bit "unconventional" but it'd work. in OnMouseEnter or OnClick, it'd toggle an internal boolean "Expanded" flag and then load the appropriate picture from a resource. i have a dislike for unconventional solutions like that.
i need to add it to a few different screens so it's probably prudent for me to have/build a component for this. i have JVCL but i don't see anything suitable offhand.
thank you for your comments/help!
I always liked the approach used by the ModelMaker Code Explorer.
For example, when you're adding a new method, some rarely-used stuff is displayed collapsed ('Options and Directives' in the image below).
(source: 17slon.com)
When you hover over the text, you notice that it's actually a flat button. (Except that it's not - I believe Gerrit does some custom painting magic here).
(source: 17slon.com)
When you click this button, a panel appears. Button is still there, but with a new image. You can click it to close the panel.
(source: 17slon.com)
The state of this toggle button is preserved between sessions. IOW, even if you restart the Delphi, next tima you invoke 'Add Method', the 'Options and Directives' panel will appear exactly as you left it the last time.
i have a dislike for unconventional solutions like that.
Over the past few years, I have grown a bit suspicious of unconventional UI solutions — which is what you seem to be creating here. Why not just use a button that the user actually has to click? That seems to be much more common in the software I use, be it MS Office or programming utilities. Also, I'd make the button somewhat larger: in the screenshot, it really seems like a tiny little thing you have to target with your mouse cursor. Oh well, and if I'm bugging you with advise you haven't asked for anyway, why not give it ">>" as a caption instead of "+"? And if you'd give it a textual caption with a mnemonic as well, it'd actually be keyboard accessible. All this should make your UI better and more intuitive. I guess.
I do apologize for not answering your question, but I hope you'll spend 2 minutes thinking whether your users would actually prefer this solution :-)
Good luck!
Actually, I think that using a TImage in this situation is pretty conventional. I have seen many people suggest using the TImage, when either the TButton, or any of its associates did not have the right amount of control for whatever the developer was trying to do.
Have you tried a TBitBtn? I think when you get rid of the text it centers whatever image you have associated with it. I just checked in Delphi 6, all I have installed on this machine, and it had the MouseMove event.
