I'm using C++Builder 10.3 with a VCL application for Windows. I'm trying to identify a specific item in an AdvPopupMenu by looping through the Items Caption and comparing the Caption to my search text using CompareText(). The Captions have an '&' in the Caption text which I believe is part of the ShortCut feature. This seems to prevent a match when comparing the text.
I have tried setting up the menu items two ways to try and remove the '&'.
//--#1 Menu Setup--
TMenuItem *NewMenuItem;
NewMenuItem = new TMenuItem(MainForm->AdvPopupMenu1);
TShortCut sc2;
sc2 = TextToShortCut("(None)");
NewMenuItem->Caption = "Google";
NewMenuItem->ShortCut = sc2;
//--#2 Menu Setup--
TMenuItem *NewMenuItem;
NewMenuItem = new TMenuItem(MainForm->AdvPopupMenu1);
NewMenuItem->Caption = "Google";
NewMenuItem->ShortCut = NULL;
Below is my loop to search for the AdvPopupMenu item.
UnicodeString SearchFor = "Google";
UnicodeString TestCaption;
for(int i=0; i<MainForm->AdvPopupMenu1->Items->Count; i++){
TestCaption= MainForm->AdvPopupMenu1->Items->Items[i]->Caption;
if(CompareText(SearchFor , TestCaption)==0 ){
//This CompareText always fails
//TestCaption looks like this "&Google" or this "G&oogle"
}
}
How can I setup the AdvPopupMenu Caption to contain no '&' and make the CompareText work?
The &s are important. Without these, keyboard users like myself will find your application more difficult to use.
I think your best solution is to use the StripHotkey function in the Vcl.Menus unit to remove the ampersand character before you pass the caption to CompareText. (In addition, instead of testing if CompareText returns 0, it's better to use the SameText function.)
That is, don't attempt to create the menu items without the ampersand character, and don't try to remove it from the menu items. Only remove the character from the string you pass to the comparison function.
Also notice that the ampersand character is not related to the ShortCut property. The ampersand character makes the next character underlined in the menu item caption, telling the user than he or she can press that key to activate the menu item, but only when the menu is open. On the other hand, the ShortCut property adds a right-aligned text like Ctrl+A or Shift+Ctrl+N or F2 to the menu item, and these shortcuts are available even when the menu isn't open. Hence, these are different features.

In Delphi 10.4 Sydney, if you select a comment, for example //xxx and then press press { on your keyboard, the editor will automatically replace the selected text/comment with {//xxx}.
The expected behavior would be to have only { on the screen, instead of {//xxx}.
How do I stop this behavior?
I disabled all my IDE experts, so this must be from the IDE itself.
This is a general feature not related to comments.
If you have anything selected and type an opening bracket like ( or {, you will automatically surround the selection with this bracket. For instance, if you select cat and type (, you will end up with (cat).
This can be particularly annoying when the IDE helps you with an if statement: If you type if and then a space, the IDE automatically inserts if True then with True selected. If you then type ( (for instance, if you want to type (a = 1) and (b = 4)), you will end up with if (True) then, and not if ( then.
To disable this feature, go to Tools, Options, User Interface, Editor Options, Key Mappings, Enhancement modules and deselect Smart Surround Keys:
I am welcoming Embarcaderos efforts to make TListView more dynamically, and was exited to see Sarina Duponts post here where you could just link the imageindex to the TListView properties in LiveBindings Designer, and even the image property to a datafield (integer) when using DynamicAppearance and TImageObjectAppearance.
But... I tried, and did almost succeed.
In my challenge I have an application where I use TFDMemTable with TREST* function to populate the TFDMemTable. All works well if I don't use the DynamicAppearance and use i.e. ImageListItem and links the datafield I want to use to the imageindex property in TListView using LiveBindings Designer.
With DynamicApperance though, there are no imageindex property to link to, but Sarina Dupont says in here post that you could link the integer field directly to the image property (and IDE/compiler will figure it out).
Well... I figured following out: My data fields (semicreated from TREST* and TFDMemTable) are not neccesserely what they seems to be. Since I am using REST/JSON, the fieldtypes are "anonymized" to WideString, actually the FieldDefs->'dataitem'->DataType is set to "ftWideString". I tried to change this value to ftInteger in hope that this would help, but I did just get this errormessage: "FDMemtTable1: Type mismatch in field for 'datafield', exepecting: WideString actual: Integer".
So... I was nearly there, and I really want to use DynamicAppearance and view several images and textfields for each TListViewItem...
...or is it easier to make a ListViewItem 'Template' dynamically and populate it with data instead, and what is the best way to do that ?
I usually try to avoid LiveBindings. The fastest, most stable and easiest way is to add items using code.
ListView1->BeginUpdate();
try {
for (int i = 0; i < arrayOfThings->item.Length; i++) {
TListViewItem* item = ListView1->Items->Add();
item->Text = arrayOfThings->item[i]->item_name;
item->Data["itemName"] = TValue::From<UnicodeString>( arrayOfThings->item[i]->item_name);
item->Data["itemId"] = TValue::From<UnicodeString>( IntToStr( arrayOfThings->item[i]->id ));
item->Data["itemDate"] = TValue::From<UnicodeString>(arrayOfThings->item[i]->item_date);
// adding the image - imgClock is name of the image field [TImageObjectAppearance ] added to items in ItemAppearance in the TListView object that uses DynamicAppereance
const UnicodeString imgClock = L"imgClock";
dynamic_cast<TListItemImage*>(item->Objects->FindDrawable(imgClock))->Bitmap = //bitmap source;
}
} catch (...) {
}
ListView1->EndUpdate();
I have a Windows Form Multiline Textbox.
I want to use Shift+Enter Instead of using Enter key to make a new line in textbox, and the traditional Enter key will be used to focus on the next control.
I mean Shift+Enter will work exactly like Enter key on normal multiline textbox (Regard to textbox maxlength --> So you cant enter newline, or current selected text will be delete when you insert newline,...)
I've tried to override OnKeyDown, to insert newline on Shift+Enter, but it doesn't work as I expected.
you'll need to override OnKeyDown and check for enter key using the KeyDownEvent's KeyCode property.
If enter was pressed and the keydownevent's modifiers property does not equal Keys.Shift you'll need to suppress the key press. Here's the documentation on how to do that:
http://msdn.microsoft.com/en-us/library/system.windows.forms.keyeventargs.suppresskeypress(v=vs.110).aspx
If shift+enter was pressed you'll need to insert Environment.NewLine at the cursor position, then move the cursor after the inserted Environment.NewLine. Here's how to do that:
How to paste text in textbox current cursor?
Here is my implementation in VB .NET.
Regard to Maxlength of the textbox and current selected text
Protected Overrides Sub OnKeyDown(ByVal e As System.Windows.Forms.KeyEventArgs)
If (Me.Multiline AndAlso e.KeyData = (Keys.Shift Or Keys.Enter)) Then
Dim intRemainCharCount As Integer = Me.MaxLength - Me.Text.Length + Me.SelectedText.Length
'' Check if have enough space to place NewLine
If (Environment.NewLine.Length > intRemainCharCount) Then
MyBase.OnKeyDown(e)
Return
End If
Dim intPos = Me.SelectionStart
Me.Paste(Environment.NewLine)
'' Reset selection start (Reset cusor position)
Me.SelectionStart = intPos + Environment.NewLine.Length
e.Handled = True
e.SuppressKeyPress = True
Return
End If
MyBase.OnKeyDown(e)
End Sub
Change the property for Accept Return for the Multiline doesn't even require coding anything, unless you have an event listening to the KeyDown, in which case you can put a condition to check if the Textbox is focussed.
I try add my own characters in keyboard.
I expand key 'z' by code to "Keyboard-en.plist":
"Roman-Accent-z" = {
Keycaps = "z mylongstringtitle ..."; // ... == \U017e \U017a \U017c characters ('z' with apostrophes and dots)
Strings = "z mylongstringvalue ...";
};
But keyboard not shown my string 'mylongstringtitle', only blank space ' ':
I can add only string 4 chars length on normal font and 7 chars on small font on 'button'. But I need add a long string.
Can I add 'mylongstringtitle' inside keycaps's string? May be I need set special parameters for long string? This is possible?
I don't think you will be able to add long string to be displayed in keyboard-en.plist. I believe the limitations of 4/7chars that you discovered are hard-coded in desire to avoid disfigured popup.
This keyboard behavior is not supported by Apple (it's not documented on http://developer.apple.com, or http://devforums.apple.com). Use of this feature in your app, therefore, is undefined behavior, which is considered programmer error.
That said, it's a neat feature. The limits of 4 and 7 characters for keycaps are hardcoded on iOS. I can't find them in any of the keyboard plists. You'd probably have to modify the keyboard binary to do what you want. (On OS X, on the other hand, this limit does not exist.)
A few alternatives exist, which you might know about:
You could modify this custom keyboard project
You could assign a custom inputView to be displayed at the top of the system keyboard
I'm trying to write something like rtf editor in BCB6 and I've encountered such problem while trying to add table to my RichEdit1:
RichEdit1->PlainText=true;
AnsiString ret=RichEdit1->Text;
ret.Insert(table, RichEdit1->SelStart);
RichEdit1->Text=ret;
RichEdit1->PlainText=false;
RichEdit1->Repaint();
This code adds formatted text (code of table) to the RichEdit1 instead of adding formatting code as plain text and displaying it like a table.
Am I doing it wrong, or it can be a problem with something else.
The PlainText property is only used by the Lines->LoadFrom...() and Lines->SaveTo...() methods, nothing else.
The Text property only operates on plain text. Reading the property extracts the RichEdit's textual content without formatting. Setting the property does not process RTF code at all, the RichEdit's textual content is replaced with the new text as-is.
If you want to insert RTF code into the RichEdit, especially if you don't want to overwrite the RichEdit's current content, you will have to use the EM_STREAMIN message directly. For example:
DWORD CALLBACK StreamInCallback(DWORD_PTR dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb)
{
int numRead = reinterpret_cast<TStringStream*>(dwCookie)->Read(pbBuff, cb);
if (pcb) *pcb = numRead;
return 0;
}
TStringStream *strm = new TStringStream(table);
EDITSTREAM es = {0};
es.dwCookie = (DWORD_PTR) strm;
es.pfnCallback = &StreamInCallback;
SendMessage(RichEdit1->Handle, EM_STREAMIN, SF_RTF | SFF_SELECTION, reinterpret_cast<LPARAM>(&es));
delete strm;
Problem solved, formatting was not added because of table code was not in {} brackets, after adding them around table code and using SendMessage, program works well.
