 | use as intellisense?

heya lukasz,
thx for this nice control! 
i am thinking about using this as a basis for a intellisense-like control
i want to type in a TextBox and on the TextChanged event i want to show the
popup and let it filter its ListBox.
i expected the property "FocusOnOpen" to help me achieve this. but the focus
after the popup is shown is not in the owner-form. a
((TextBox)sender).Focus();
doesnt help.
do you have an idea how to solve this?
best regards

 | RightToLeft forms problem
AbdelRahman Doghish | 1:01 2 Feb '10 |
|

Dear,
When I try to add a form that is has the property (RightToLeft = RightToLeft.Yes); the popup throws the following exception (Error creating window handle.).
Note that the problem is solved when I changed the value of this property only and make it (RightToLeft = RightToLeft.No)
Code:
frmDetail.RightToLeft = RightToLeft.Yes;
Popup popupScreen;
popupScreen = new Popup(frmDetail);
//The last line throws the exception
Is there any solution for this problem because I want to add a RightToLeft form to the popup?
Thank you very much in advance for your cooperation.
Best Regards,
AbdelRahman Doghish

| Transparency

Its a great resource! But i have 1 question. There is any posibility to accept a transparent user control and make the popup transparent?
This is how i see the image if i set the transparency: http://img267.imageshack.us/i/24902031.png/[^]
This is how i see the image withouth the transparency property set to true (the problem is that that shadow should be semi-transparent, but the backcolor is set to white): http://img442.imageshack.us/i/55940912.png/[^]

I try to use Simple popup with Mono.
More info here:
CheckBox ComboBox Extending the ComboBox Class and Its Items[^]
The version used in CheckBoxComboBox does not use the P/Invoke AnimateWindow
However, the code still not works in Mono.
Same traceback appears when testing Mono with PopupTest.exe
Any hints what can be done to get the code work with Mono?

It looks like Mono’s Windows Forms still doesn’t work exactly like .NET’s Windows Forms.
Anyway… in the Popup.cs file, in method OnSizeChanged add "if (content != null)" checking… this fixes the NullReferenceException.
But the popups still don’t look very good because of bug in Mono, look here: http://go-mono.com/forums/#nabble-td22184714[^]

You may add this code as well to the Popup class, it fixes almost all bugs related to Mono.
protected override void OnLayout(LayoutEventArgs e)
{
Size suggestedSize = GetPreferredSize(Size.Empty);
if (AutoSize && suggestedSize != Size)
{
Size = suggestedSize;
}
SetDisplayedItems();
OnLayoutCompleted(EventArgs.Empty);
Invalidate();
} Łukasz

Thanks, great!
Any problem having this fix in .NET too or should the following be used?
public static bool IsRunningOnMono()
{
return Type.GetType("Mono.Runtime") != null;
}
protected override void OnLayout(LayoutEventArgs e)
{
if (IsRunningOnMono())
{
Size suggestedSize = GetPreferredSize(Size.Empty);
if (AutoSize && suggestedSize != Size)
{
Size = suggestedSize;
}
SetDisplayedItems();
OnLayoutCompleted(EventArgs.Empty);
Invalidate();
}
else
{
base.OnLayout(e);
}
}
I have not been able to fix my intended usage yet: CheckBoxComboBox uses an older version of Simple Popup, the test application itself is not working with Mono the plugin that uses CheckBoxComboBox has other issues too. Upgraded Simple Popup works slightly better.

Checking for Mono would be good
private static bool? _isRunningOnMono;
public static bool IsRunningOnMono()
{
if (!_isRunningOnMono.HasValue)
_isRunningOnMono = Type.GetType("Mono.Runtime") != null;
return _isRunningOnMono.Value;
}

| ToolStripDropDown Not Showing
winheart | 22:47 28 Jun '09 |
|

Hi,
I had a GroupBox which contain so many text boxes and labels alligned like a data entry form. i added one button and add this code in the button click.
ToolStripDropDown tspopUp = new ToolStripDropDown();
tspopUp.Margin = Padding.Empty;
tspopUp.Padding = Padding.Empty;
ToolStripControlHost host = new ToolStripControlHost(CategoryPanel);
host.Margin = Padding.Empty;
host.Padding = Padding.Empty;
tspopUp.Items.Add(host);
tspopUp.Show(GroupBox1,txtcategory.Location);
in a plain form if we add this, it will work nicely but if lot of control inside a form it will not popup. it's very bad.
How people told this code as excellent, i don't know.

Hi,
Well, you wrote to little I could help you. I've testes a form with 4 groupboxes, each of them contained 40 labels, 40 textboxes and 40 buttons, and all worked fine. Which version of .NET do you use? Have you installed latest service pack for the .NET you’re using?
Anyway… some time ago I’ve read an article which said that there is a bug in Windows Forms which occurs when there are very many controls on a Form. Maybe you had that “pleasure” to notice that bug. I don’t know.
Regards,
Łukasz

hai,
i am using the latest version to .net frame work. in my form i have lot of text boxes and label. i am added panel and trying to host that control in the toolstip host control. but it was not poping -up. After that i made it in a user control, then it start showing.
After this i implement this same user control in a DataGridView for populating data on clicking on the button in each row according to the key value in each row. But it disappointed me very much.Only once the data will get populate. next time onwards data is populating to the grid. but it's showing the frist populated data.
Can u check this dynamic databinding to a toolstripdropdown while clicking on each row of datagridview.

| Use as a ToolTip
Bob Carboni | 8:16 18 Jun '09 |
|

This is a very nice control, and was easy to setup and start using. I have a couple of questions about using this control as a tooltip, and I wonder if you have already done a similar project.
1. I was considering using this as a tooltip for a TreeView. I want to show a tooltip when hovering over each node. However, since a TreeNode is not a Control, and does not have a MouseLeave event, I tried to display the popup when the mouse is moved over the tree itself. This works to display the popup, but after the popup is visible the MouseMove event of the TreeView is no longer called. This makes it difficult to determine when to hide or redisplay the popup. Do you have any suggestions how to use this as a tooltip over a tree?
2. As a tooltip, it would be nice to have delay properties for display and redisplay like the ToolTip class. Have you given any thought to this?
|
|
|
|
|
|
|
Thank you, I am glad you like it.
1. Did you set FocusOnOpen property to false so the popup does not steal the focus? See the grid-example, I believe you want to achieve something similar.
2. Yes, time permitting I shall create a base class for tooltip.

After some testing, I was able to successfully create a custom tooltip over a treeview by using a Timer with the mouse events. The code looks something like this:
Class Variables
Popup toolTip;
CustomToolTip customToolTip;
Timer toolTipTimer = new Timer();
TreeNode toolTipNode = null;
Initialize Code
toolTip = new Popup(customToolTip = new CustomToolTip());
toolTip.AutoClose = false;
toolTip.FocusOnOpen = false;
toolTip.DropShadowEnabled = true;
toolTip.ShowingAnimation = toolTip.HidingAnimation = PopupAnimations.Blend;
toolTip.AutoSize = true;
toolTip.Resizable = true;
toolTipTimer.Interval = 1500;
toolTipTimer.Tick += new EventHandler(toolTipTimer_Tick);
tv.ShowNodeToolTips = false;
Events
int nStartX = 0; int nStartY = 0; int nLastX = 0; int nLastY = 0;
void toolTipTimer_Tick(object sender, EventArgs e)
{
if (toolTipNode != null)
{
toolTipTimer.Stop();
customToolTip.TipText = toolTipNode.Text.Trim();
toolTip.Show(this, nLastX + 10, nLastY + 50);
}
}
private void tv_MouseMove(object sender, MouseEventArgs e)
{
TreeNode node = tv.GetNodeAt(e.X, e.Y);
if (node == null)
{
toolTipTimer.Stop();
if (toolTip.Visible)
{
toolTip.Close();
}
}
else
{
if (!toolTipTimer.Enabled)
{
toolTipNode = node;
toolTipTimer.Start();
nStartX = nLastX;
nStartY = nLastY;
}
else if ((e.X < nStartX-5) || (e.X > nStartX+5) || (e.Y < nStartY-3) || (e.Y > nStartY+3))
{
toolTipTimer.Stop();
if (toolTip.Visible)
toolTip.Close();
}
}
nLastX = e.X;
nLastY = e.Y;
}
private void tv_MouseLeave(object sender, System.EventArgs e)
{
toolTipTimer.Stop();
toolTip.Close();
}
This works nice to keep the tooltip displayed until the mouse is moved again. I might try a second timer to close the tooltip after a delay.

I’ve created a code which uses NodeMouseHover event instead of MouseMove. You may take a look at it:
public partial class Form1 : Form
{
public Form1()
{
Control.CheckForIllegalCrossThreadCalls = true;
InitializeComponent();
_popup = new Popup(_popupPanel = new Panel()
{
AutoSize = true,
AutoSizeMode = AutoSizeMode.GrowAndShrink,
BackColor = SystemColors.WindowFrame,
Padding = new Padding(0),
})
{
AutoSize = true,
FocusOnOpen = false,
};
_popupLabel = new Label()
{
AutoSize = true,
BackColor = SystemColors.Info,
BorderStyle = BorderStyle.FixedSingle,
Dock = DockStyle.Fill,
ForeColor = SystemColors.InfoText,
TextAlign = ContentAlignment.MiddleCenter,
};
_popupPanel.Controls.Add(_popupLabel);
_popup.Opened += (s, e) =>
{
object o = new object();
System.Threading.Timer timer = null;
Action close = () =>
{
if (_popupLabel.RectangleToScreen(_popupLabel.ClientRectangle).Contains(Cursor.Position)) return;
if (timer != null)
{
lock (o)
{
if (timer != null)
{
timer.Dispose();
timer = null;
_popup.Close();
}
}
}
};
_popupLabel.MouseLeave += (s2, e2) => close();
timer = new System.Threading.Timer((_) => Invoke(close), null, 2500, -1);
};
}
Popup _popup;
Panel _popupPanel;
Label _popupLabel;
private void treeView1_NodeMouseHover(object sender, TreeNodeMouseHoverEventArgs e)
{
_popupLabel.Text = e.Node.ToolTipText;
_popup.Size = _popupLabel.Size;
_popup.Show(treeView1.RectangleToScreen(e.Node.Bounds).Location);
}
} It’s only a draft, but finally I’ll create a base class for tooltips using this code.

I'm using this nice popup to pop a MonthCalendar inside a MaskedTextBox so that the user can enter or pick dates easily, the code is simple,but the popup's size is not enough to show the whole calendar(the proper should be (322,185) but it's now (178,155)).

| commercial distribution question
Silent Winter | 4:15 5 May '09 |

I have read the license agreement, and I am still wondering about some things.
As a contributor, the agreement states that all recipients of the software would be able to re-sell the software. Is this a misinterpretation? I would not be able to use this if all software that has this popup must be able to be reproduced and redistributed by buyers.
I do not fully understand the copyright requirements for software distributed without code.
Thank you for your help.
|
|
|
|
|
|
|
Paragraph 4 (commercial distribution) states that you may include the Popup in a commercial product (application), but as a creator of the popup I disallow embedding and/or re-selling this control in libraries/packages/component packs/etc.
So re-selling the Popup maybe is not prohibited by the CPL license, but by myself.
You can use of course the binaries in your software (or compile-in provided source code).
Regards,
Łukasz

Thank you for your quick response.
I was not looking to sell your popup as a featured item, but simply to use it in a distributed application. I had already made a popup control, and I was looking to add resizing capabilities when I found your control.
For use, it sounds like I will have to keep your control in its separate project, and derive off of it elsewhere for the specific functionality I need to add.
As far as copyrights, there was nothing in the license about including your copyright in the distributed application. This is what I will continue to assume unless informed otherwise.
Again, thank you for your response, and your work in making an excellent control.

You have to link your project to my dll file or use my original projects; if you include my code in your project or make changes to the code, you have to release the code under CPL license as well. So you're right, you should derive from it in another project to add specific functionality. You don't have to include copyright in the distributed application; besides, it's in the PopupControl.dll file's properties.
Here there is some "human-readable" information about CPL license: http://en.wikipedia.org/wiki/Common_Public_License[^]
I'm glad you like my control.

Łukasz

Hello!
Nice control, thanks!
But, i develop app that must be crossplatform via Mono (2.4)
Mono Migration Analyzer (http://mono-project.com/MoMA[^]) says that only ONE ussue is present - invoke call of AnimateWindow.
It is very pity for me.
How do you think, is it possible to rewrite that function functionality on pure .NET code?
Thanks!
|
|
|
|
|
|

Well, I think it is possible, but it wouldn't be very easy, because it would require to 'mess' with custom regions. I've tried it once but finally I've replaced it with AnimateWindow API.
