VB Forum / Controls / July 2008combobox hover style
Hi... i'm creating an user control where there is a flexgrid. i need this flexgrid to hover over the other objects and even the form border, just like the combobox list.. is it possible... tks... ps: i'm using vb6. > Hi... > [quoted text clipped - 8 lines] > > ps: i'm using vb6. Place it on it's own form of same size as the Combo. Use the SetWindows api setting it topmost. Make it resizeable to follow the Combos dropDown method. Tks a lot... Just 1 more question... How can i retrieve the Left and Top of the user control on the parent form? I need to position it under the user control text box... I've been strugling with it for about 4h now... >> Hi... >> [quoted text clipped - 12 lines] > Use the SetWindows api setting it topmost. Make > it resizeable to follow the Combos dropDown method.

The form is a container for the TextBox control. (wasn't it a ComboBox -last time). You're placing the control on the form. The TextBox.Left and TextBox.Top are measured relative to the Forms (containers) ScaleLeft and ScaleTop in the same units as the Forms ScaleMode -Twips, Pixel or whatever you set the ScaleMode to. So if you set the TextBox.Left and TextBox.Top to (0,0), then the textBox TopLeft corner lay in place. First you need to set the forms width and height to the size you want the TextBox to be. Then you set the TextBox.Width and the TextBox.Height to the size of the Form.ScaleWidth and Form.ScaleHeight. This should be done in code, so you can resize both as a single unit. /senn Actually, as Jeff Johnson said, i'm creating a replacement for the combobox, where the list is a flexgrid control. The textbox and button are place in an user control (.ctl), and the flexgrid is placed in a form inside the UC . i've tried a lot of diferent combinations of code, and none of them worked out as should... if my mind ain't tricking me, scaleleft and scaletop returned 0... or something like it, but the grid where place very far from where it should be. tks... >> Tks a lot... >> [quoted text clipped - 23 lines] > > /senn > i'm creating an user control where there is a flexgrid. > > i need this flexgrid to hover over the other objects and even the form > border, just like the combobox list.. > > is it possible... If you're saying that you're trying to create a replacement for the combo box which uses a flexgrid as its dropdown list then you've taken on quite a task. One of the trickiest things about the combo box is that the dropdown list has the ability to extend beyond the borders of its parent window, something that is not normally permitted. To do this you have to fiddle around with re-parenting the flexgrid while it's displayed. I'm not sure if there's an article about this on www.vbaccelerator.com or not, but if something like that is anywhere, that would be the place. Good luck. hey there... i found out about the setparent api, and it worked... but i still cannot "attach"/ set up the position... scaleleft and scaletop returns 0... usercontrol.top and usercontrol.top returns some number that is not the position... clearing the parent control, i assume that i must get the usercontrol's absolute position on the window, right?? getwindowrect,maybe? or it does no apply? tks. >> i'm creating an user control where there is a flexgrid. >> [quoted text clipped - 13 lines] > > Good luck. > hey there... > [quoted text clipped - 10 lines] > > tks. You're expressing yourself incoherently. That's why the answers do not come off. SetParent API is not used to set positions. I told you previously how to set controls (TextBox, Combo, or FlexGrid) - no APIs should be used. SetWindowPos API is used to set position and order of a form (a Form-Object). You'll be best off droping this and be looking after somthing useable allready made up. /senn >> hey there... >> [quoted text clipped - 23 lines] > > /senn i know that this API doesn't set position... with this API i was able to make the flexgrid stay over all the elements, and even form borders... just like the combobox list. reading what i wrote, i can see that it was realy bad written... all subjects mixed up... i had here 2 subjects running. 1) make the grid hover over the others elements... DONE, clearing the SetParent API. 2) set up the grid position in f ( ) of it will always be placed right under the textbox of the user control. >>> hey there... >>> [quoted text clipped - 35 lines] > 2) set up the grid position in f ( ) of it will always be placed right > under the textbox of the user control. FlexGrid1.Left = TextBox1.Left FlexGrid1.Top = TextBox1.Top + TextBox1.Height not easy like that... the flexgrid is place in a separated form... the form isn't related to the user control, this way, isn't related to the text box.. the text box is at (0,0) , but the user control where it's placed is in another position on the mdi child form... so i must get the user control position to just then place the flexgrid. scaleleft and scaletop returns 0, both... usercontrol.extender.left / .top returns some value that is not right... >>>> hey there... >>>> [quoted text clipped - 38 lines] > FlexGrid1.Left = TextBox1.Left > FlexGrid1.Top = TextBox1.Top + TextBox1.Height > not easy like that... > [quoted text clipped - 8 lines] > scaleleft and scaletop returns 0, both... > usercontrol.extender.left / .top returns some value that is not right... First, I do not think you should use a MDI-form. Set position of any forms with below API. If you are using childforms or forms been set with SetParent API, SetWindowsPos API won't work unless using the const SWP_NOZORDER. -I found out that. Do you have the KPD-Team API guide, then use the SetParent API as shown in their example - if you are still using it. But use below to set positions. When not child forms change SWP_NOZORDER with SWP_SHOWWINDOW or SW_SHOWNORMAL. Course, change 0, 0, Me.ScaleWidth, Me.ScaleHeight to suite your needs. /senn Const SWP_NOZORDER = &H4 Const SW_SHOWNORMAL = 1 Const HWND_TOPMOST = -1 Const HWND_NOTOPMOST = -2 Const SWP_NOSIZE = &H1 Const SWP_NOMOVE = &H2 Const SWP_NOACTIVATE = &H10 Const SWP_SHOWWINDOW = &H40 Private Declare Sub SetWindowPos Lib "User32" (ByVal hWnd As Long, _ ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, _ ByVal cy As Long, ByVal wFlags As Long) SetWindowPos mWnd, HWND_TOPMOST , 0, 0, Me.ScaleWidth, Me.ScaleHeight, SWP_NOZORDER |
